Hi, I use Rose Connect v3.0.27 on my iPhone SE2 and in connection with my RS150.
In general it is very feature rich but many times the app and the device live ‘their own lives’, meaning that actions done in the app are not always correctly reflected on the device.
One example is Rose Radio: changing the frequency with the wheel in the app sometimes does not move the needle on the device.
Another bug I found is related to Tidal video:
Whichever video you click on, always the most left video (= the first of a category) will be played or started again playing.
So clicking on Tears For Fears results always in visualizing the video of Tame Impala.
