FP3+ already on Android 11 since 1.5.
I don’t know if it’s because of the “Did you know? /e/OS updates are full blahblah” popup that I got when tapping “Install”, but the percentage displayed near the “Preparing for first boot” and “Finalising package installation” progress bar is stuck at 100% despite the overall process seemingly going on as planned and the bar gradually filling up as usual.
