I have an IMAP email account, which I use in the email app on my Samsung Galaxy tablet, in Thunderbird on my Ubuntu laptop, and in SeaMonkey on my Windows laptop*.
A while ago, the TLS cert on the mail server expired. In Thunderbird and SeaMonkey, I could override the warnings and still get my email. The Android tablet did not offer any mechanism to achieve this. That’s okay. The thing is, I now do have a new up-to-date TLS cert on the mail server, and the tablet still refuses to sync my email.
What’s going on here, and how can I get my email back on my tablet?
* The same laptop, actually. Not that this is relevant.
