It is now for the second time that all IMAP email accounts, are no longer present. I don’t know wether the accounts on the mobile phone are deleted or K-9 does not find the data. The fact is, K-9 is like the first installation, and I have to set up everything again. What shall I do, so I don’t have to set up the accounts again every 3 weeks ?
My mobile phone is a Huawei P10 lite with Andorid 8.0 (WAS-LX1A) and
K-9 Mail V. 5.727
Thanks for your support.
