Links not working in any email app

[LeslieR]

It started with getting a number of pop-up articles whenever I hovered over an app on my phone. I think I fixed that, but now hyperlinks in all 3 email accounts - - Outlook, Gmail and Yahoo - - don't work. Can't even unsubscribe from emails. Nada. I reset my settings last night, but nothing helped. Don't know if this is a system issue or just mine alone. Need help. I use my phone extensively for business.

@LeslieR hello, follow these steps: go to Settings/Applications and at the top you will see the option Choose default apps, look for the option Open links, and in each application that does not work for you -activate the option -Open supported links. Greetings.

When I do this, “email” does not appear in the Installed apps.  How do I add it?
