Did you do the firmware update via OTA? I’ve had problems with either Yuneec server or local server timing out during updates. That’s no good in my opinion. I only use the SD card method and do the ST first, rebind to model, clear out SD card, put Hex .bin file on card into camera and update accordingly. The last and only firmware available has been great and worked fine across all my THs (6 now - don’t ask... I’m obsessed) and actually helped clean up one that had pervasive compass warnings but no noticeable flight misbehavior. I had replaced the GPS/compass board twice on this model. It took changing the status LED and a firmware reinstall to fix.
If your GUI is on a laptop, you can hook up the H, set it outside and look at the satellites it’s finding. A properly calibrated and working GPS/compass module finds GPS coordinates much faster then one with problems. If it’s “thinking” too much then for sure push Yuneec for a warranty issue. That’s a whole other issue that’s frustrated many and you may discover buying a new GPS/compass module is quicker then dealing with warranty.
