Location tags on reminders not working Belgium.
Reminders have no location. Release notes don't mention region for this functionality

Same thing over here in Germany.
I guess the location is saved anyways (since every image that I have taken with the glasses has a geotag) but maybe not directly displayed in the reminders section.
Probably some sort of EU-Dataregulationlawthing...
Have you tried asking Meta AI for the location the reminder was set? Maybe she can help you with that.
