Hi all @here, sorry you’re having issues with your Trackers. There can be a multitude of reason why workspace can get corrupted and it might be same or different between all of you why it happens.
I will close this topic for now, but please report a separate Bug if it still happens to you, here is How to report bugs . Last point is especially important so we can investigate quickly. In this case corrupted workspace folder from your SD card which doesn’t boot up will give us the answers. Or exact reproduction steps which lead to the issue.
@mat.on.the.moon going back and forth between Mini and Plus is only supported if they are both on latest FW versions, otherwise we cannot guarantee project compatibility.
With SD cards of course, please eject them safely.
