adding r2 keys didn't work. it gave me random code error messages instead of catching it and making it readable. all for the low price of having nude people in ads pop up on my screen and a giant fake continue button when I'm trying to go through the setup phase.

I use this app to keep my data synced to my NAS. It works really well in the background without me ever having to worry about it. Except recently it was timing out trying to connect to the NAS via SMB. A review here told me to enable nearby devices permissions and that worked. Otherwise the app is really reliable.

Clunky, but works in the end. SMB sync stopped working with update to Android 17, with no useful error message as to the problem. Some troubleshooting later I found that granting the app the Nearby Devices permission in my phone's settings allowed it to once again connect and run my sync. Would have been nice to have the app let me know this was now needed, or have some changelog or support article available.
