When I hit the Archive button on an email in Mailspring, the email disappears from Mailspring’s inbox and appears in the archive folder as expected.
However, on other clients such as Spark (Android) and Mailbird (Windows), the archived message is still visible in the inbox folder – as well as the archive. I have left time for Mailspring to resync (overnight) and even closed/reopened the app, but no change.
I assume this is a bug but not sure how I can troubleshoot it?
