For the ladt 2 weeks, whenever I open the yahoo mail app on my I-pad mini, I get a pop up telling me to update the app by the 23rd May (tomorrow). I tried to do this last week but was told I needed at least IOS10. Since I am on IOS9.3.5 and there being no updates from Apple to do, I cannot upgrade to rhe new app so I stand to lose my messages and settings. Very clever Yahoo for failing to check where IOS 10 is actually loaded. My UK I-pad is not of your standard so Inlose through your inefficiency. Also, why can I not send an email to yahoo from yahoo mail app? Chech with Apple next time you do this stunt!
