Millions of users of Yahoo mail have had problems with the app, with the provider saying the issue may not be fixed for another day.
They said people could uninstall and reinstall the app – but warned them not to do this if they didn’t know their log-in credentials, as they could get locked out.
Yahoo Customer Care said: ‘Thank you for your patience as we have worked to resolve an issue with our Apps today.
‘A fix has rolled out, but this may take up to 24 hours to reach your device.
‘To achieve a faster resolution, you can uninstall and reinstall your App.
‘Please note: We recommend not uninstalling your App unless your login credentials (password etc.) are known, or your recovery channels are up to date, as you will be required to log back in upon reinstall.’

Many users on Twitter sent messages to their support account, saying they had not managed to access their emails after trying to fix the issue.
One man angrily tweeted: ‘My password doesn’t work and the app now says there are no recovery options. WTF? At least the system tried to send me a 2FA message during the day now it seems my account is fxxxxked?…’
Yahoo replied that they were ‘sorry to hear this’ and asked them to contact them privately to discuss potential support options.
They advised Android users: ‘For Android Devices: 1) Long press the app icon. 2) Click the info icon on the top right corner to open the app settings. 3) Scroll down to the usage section and storage row, and open it. 4) Clear cache and clear data. 5) Reopen the app and it should work as usual’
