I have the same issue.
Normally the issue is with the SSA tracker, so first thing to check is if your trace is showing on the Garmin web side. If it is, then you need to contact Pedja the creator of the SSA tracker to fix it.
However recently my trace is not showing even on the Garmin share page, so I suspect an issue with my Inreach or settings. I reset it but still no trace. Which setting did you change?
