Unfortunately - after installing the new firmware version 15.33, the Fenix watch again crashes or restarts during navigation.
Reporting the problem regarding the Fenix suspending or (and) restarting to Garmin technical support ended with Mr. Jan (Polish support), recommending that I reinstall the map.
In addition, Mr. Jan suggested that the errors I found in the watch are not faults and I should send them to Garmin's design department.
I also reported the errors of the Polish translation in the watch menu then again Mr. Jan asked me to take a screenshot of the watch :) I don't know - how to take a screenshot of the watch is one. Two - will support really fix menu translation errors only in these specific examples?
In general, 8 days have passed and Garmin support has not found the cause - why the Fenix 8 watch crashes or restarts during navigation?
