I’m currently using Mailspring 1.10.8-8ea2a61f. When I start Mailspring it says "An update to Mailspring is available (1.1.0-6193b33c) with Download and Dismiss options.
I installed the top option, “Linux (Auto-updating snap)” but ended up with 2 versions of Mailspring, one of which had no content. I assume that was the Snap version and I had originally installed the deb version.
I removed the snap version and downloaded the mailspring-1.11.0-amd64.deb version but opening that just gives me the option of uninstalling it.
I have lots of email accounts and I don’t want to have to set them all up again.
