Every 2 or 3 months the activities "steal" the memory capacity for CIQ stuff! I have 70 activities on my FR245 and the CIQ app shows less free memory. That happens after 2 oder 3 months. After deleting old files in the activity folder the capacity is back to normal for watchfaces etc. Why does that happen? The watch syncs daily with the Connect Mobile app. Once a week I use Express for sync. If I wouldn't deletes the files manually would the watch delete them itself or would the recording of the activity stop? It's not the first time I notice that. My FR735 didn't have these problems. From time to time old files were deleted after a sync via Express. I had only one message with full memory during the years I used the watch.
