Running on a Samsung Galaxy S21, Android 14, One UI version 6.1. Android security patch Jan 1, 2025. I've tried both the most recent stable version of the Android Thunderbird app as well as the beta version, both from the play store. Both successfully import from the desktop app using the QR code. At least the process seems to complete without any glitches and my two mailboxes show up on my phone. I'm connecting to servers at Pair networks, which works from the Thunderbird desktop (Max OS, Sequoia 15.3). I have two mailboxes, both routed to the "unified" view. I'm pretty sure the mail servers are running IMAP, but there's always room for doubt. I'm assuming that the little circle of arrows in the menu for the unified view does a manual sync, although I reconfigured the polling for 15 minutes and waited significantly longer than that and still nothing. I can send e-mails from my gmail account and they arrive at the desktop app in short order but don't get to the Android app. I'm assuming here that both the desktop and Android programs will get all emails... I am running BitDefender on my phone, although I've tried disabling that and still nothing when doing a manual sync. It doesn't appear that I can send e-mail from my phone either. Messages just sit there in the outbox, even after clicking "send messages" on from the three-dot menu drop-down. I can send e-mail from the desktop client. I have the app running on my laptop all this time. I'm at my wit's end, any suggestions? Thanks, Erick
