This has been discussed in the forum, but we haven't heard anything about it since. It's still happening to ma multiple times a day, especially when I have long walks (more than 30 minutes). It can happen multiple times in the same activity (when I see the IQ... I pause the activity, choose Resume later, then resume it and continue my walk and then some time later it happens again)
It was discussed here: Both CIQ datafields in the activity crash suddenly
It happens with this (beta) datafield every day: https://apps.garmin.com/apps/4db70717-f1c9-442a-9f18-9d81c31e2ea0 but also with different others on fr965 27.09
