Can't Download: Suunto Vyper Novo

[John Skovron]

Can't download from dive computer. 

Subsurface 6.0.5436. Android 16 on Samsung Galaxy Ultra 25.

DC switches to data transfer mode as expected. 

App crashes if DC is connected (via USB) first.

App never downloads any dives if connected after app launched. (Just sticks in downloading mode indefinitely.)

Same if DC is forgotten and added.

Tried fresh boot.

Tried clearing app cache.

Tried Developer Options: Default USB configuration. 

Tried while offline (to mitigate current poor connectivity on liveaboard).

Appreciate any suggestions. 

Happy to provide additional info. 

Thanks
