#fantasysports API returning persistent 403/401 on roster endpoint since July 24
I'm the developer of a registered Fantasy Sports API application (Client ID: dj0yJmk9TmtQaVFTZE16NVNEJmQ9WVdrOVJWZDFZMGcwY1c0bWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTYw). Since July 24, 2026, roster requests (GET /fantasy/v2/team/{team_key}/roster) have been intermittently, then consistently, returning 403 Forbidden (occasionally 401). As of July 28 this is happening on essentially every request, across all 3 linked accounts and all teams.
This isn't a stale token issue. My logs show a completely fresh access token, issued moments earlier via a successful oauth2/get_token refresh grant (200 OK), being immediately rejected by the roster endpoint. Request volume is very low (roughly 200-250 requests/day across 3 users), well below anything that should trigger rate…

Fantasy API error
- App ID: eg7WXktc
- Endpoint: https://fantasysports.yahooapis.com/fantasy/v2/game/mlb
- Error: This application is not authorized to perform this action
- Request ID: 5g9krchl6h5iu (from this test — traceable on their end)
- Confirmed: fresh OAuth token via full re-consent, correct scope requested, "Fantasy Sports - Read" permission checked and saved, yet still rejected; a different Yahoo API (openid/userinfo) correctly accepts the same token and returns a normal scope-mismatch error, not a blanket rejection — ruling out a token problem.

Print Icon available on groups of emails.
I want to transfer several emails to Dropbox. I got instructions that I could check the boxes next to each email and then click on the print icon, save all the emails to PDF files and transfer this file to Dropbox. However, I've now been told that I need to open each email to get a print Icon. I think you need to create a print icon for a group of unopened emails so I can transfer them as one file to dropbox.

RESTORE NOTEPAD
Thank-you for addressing my concerns. When you consider the voluminous amount of data many of us have meticulously gathered and organized in notes, Yahoo made a very cruel and thoughtless decision by eliminating Notes. Please RESTORE this essential item. Regards, Robert Tartell (punter75@yahoo.com)

Misspelled Top Contacts should be deletable
I was told by a customer care associate that "The option to edit or delete a misspelled top contact is not possible," and I can't believe that statement. Something like that should absolutely be editable and/or deletable! Please make it so. Also, I am still experiencing the issue of missing messages.

Developer App Help
fantasysports
I created a Yahoo Developer app for FanGrid Sports and need Yahoo Fantasy Sports API read access for fantasy football league data.
The app currently does not show Fantasy Sports under API Permissions, and OAuth returns invalid_scope when requesting the fspt-r scope.
Can Fantasy Sports Read access be enabled for this app?

New yahoo email feedback.
I've been a Yahoo Mail user for nearly 20 years, and I'm extremely disappointed with the new version. One of the reasons I stayed with Yahoo for so long was because it had its own unique interface. The new design feels like a copy of Gmail, and it has lost the simplicity and layout that made Yahoo Mail easy to use.
I would like the option to use the previous Basic Mail or the classic interface. Not every long-time customer wants the redesigned experience, and it would be appreciated if Yahoo allowed users to choose the version that works best…

#MyYahoo - New Home Page
The proposed "New Home Page" is a definite BAD idea. The current Windows version provides a compact and user content selected format in 3 or 4 columns with convenient links to articles, The new format requires excessive scrolling to find links of interest.

Your programming team needs to bring back "View" and "Preview Panes" for Yahoo Mail.
he new updated Yahoo mail is missing significant items. I have multiple accounts that are on the left side of my Yahoo mail browser window for each email account. They are no longer there and now I have to log out to log into each email account. The prior account had each account listed on the left side.
Also, there is no "VIEW" to see attachments like photos and documents. You must return to this. It is what separates you from the "mear mortal" email programs.
Last, there is no way to see the preview panel, whether to the right…

Make all Yahoo night mode beyond the start page
Hello- Recently the Yahoo start page went to a night mode look which I much prefer as easier on the eyes to read. Was wondering if the rest of Yahoo will switch over to this, such as the mail and search results. I originally e-mailed customer care, and they suggested writing you folk as well. Thanks.
