I use Android and don't know iOS well enough to go deep into the details. But your phone should have some kind of list of apps with the permissions you allow them. The answer is almost certainly there. This comes up fairly often on r/Garmin and that seems to usually be the solution. I hope it helps. 🙂
Edit to add: the "heat acclimation" is ... you're probably not missing much there. But correctly adjusted VO2max is probably worth having if you use that feature or the training summary based on it.
