thinks I'm in Sweden
Yahoo thinks I'm in Sweden, probably because I once briefly selected Sweden as a location for my McAfee VPN service. All menus, etc., are in Swedish. Auto-correct fights me constantly, replacing what I've typed with jibbrerish (I suspect it compares what I've typed to the Swedish language and makes a substitution). Can't find an answer on any of your help screens and I'm ticked off at the idea I should pay for help. One other problem - I can't sort my messages by sender which for me is essential to getting rid of the junk I don't want.

Hi there. The option to sort by sender will be available once you have turned off ''Group by conversation'' by going to Settings>More Settings>Viewing email.
As for location, check if your account info has your correct location set: https://help.yahoo.com/kb/language-location-preferences-yahoo-sln16027.html In case you're using a VPN, that can interfere with your experience. If you need additional help, contact us on Twitter/X at @YahooCare or on Facebook at our Yahoo Customer Care page. If you do not have a social media account, we are available at help.yahoo.com through the ''Contact us'' link.
Thank you,
