Yahoo mail has stopped working on Ipad and I phone

Same here and have tried uninstalling/reinstalling app but still does not work - just a quick flash of Yahoo!Mail and it goes back to app icon. Can get onto Yahoo mail if I go through safari/search/Yahoo mail/ log in and same with Google but absolutely NO joy using the app (exactly same on iPhone and iPad Pro)

Same here. No I have not enabled authenticator for yahoo. I went to check my email on the app this morning and it appears it's crashing. There is a problem.

IOS was automatically updated last night and since then I can't open the Yahoo app. I've deleted it and reinstalled it and still having the same issue. If I reset all accounts in the iphone setting I can then open the app but once I input my login in details it crashes. I can still access my emails via the iPhone mail app

You may have enabled Authenticator for Yahoo --> Generate and manage third-party app passwords | Yahoo Help

HS there been any resolution to this as mine is crashing too?

Same here after 17.3.1 update

Same here.

tried to remove App, remove account...

reinstall App -> Crash when loading

they probably fixed it. I re-installed one more time the app this morning, and now its working fine.
