mail disconnecting from gmail
Since upgrading to Mojave, the Mac Mail app has been repeatedly disconnecting my gmail accounts. I have used these accounts with Mail for years without issue prior to this. My credentials with the gmail accounts are valid, and typically just clicking repeatedly on the tilde icon next to the disabled account eventually gets it working again, without me having to enter any new credentials - evidence that the credentials are fine.
Are others having this issue recently?
What can I do about this nuisance? Unless I notice the tilde symbol, I fail to get alerts that I have email pending on gmail.
