[BUG] USB mode set to Garmin fallback to MTP anyway

Dear all,

On my f5+ (fw 6.00) I've set the USB mode to "Garmin" instead of MTP to get the prompt when connecting the watch to my Mac.

The prompt shows up correctly when I connect the watch to my mac, asking me "Use MTP" (yes / no). But even if I choose "No", the watch will switch to MTP mode a few seconds later... Which is most likely not the expected behavior in this configuration...

I would like to avoid the AFT window showing up at every watch connection.

Do anyone else can confirm that this option is not working ?

Thanks.
