I got the Message “unsupported Device” while trying to install Ratio on my Pixel 3a.
Phone: Pixel 3a
(I used the the Google type C - C Cable included with the Phone)
My Steps to fix
Here are the steps I did, to got it working to install Ratio Pro App
Uninstall Blloc Desk with cleanmymac (don’t how to do on Windows, I want to get rid of the settings). restarted computer. installed fresh Blloc.
While this I installed Ratio Light with standart porcedure.
Then I was able to install the Pro version. At first stuck on the ‘enter licence key’ Step, I guess this was due to Server Issue. Restarted Blloc Desk and got to the next step. Then the setup stuck at 100% downloading. Granted ‘Storage’ Permission and restarted Blloc Desk and it worked then.
After finishing the Blloc Desk setup I am now able to grayscale Apps and apply costum brighntess which I guess is only a pro feature and have Ratio Icons as well, so this was kinda ‘update Ratio light to Pro’ procedure.
Having Ratio Light installed on my Phone helped me with it. Also it helped reinstalling Blloc Desk a few times, then I got to the installation.
Hope this will help
