I posted this in another thread which looked similar, but which now looks to be a separate problem, so reposting here:
Qu-Pad on iPad works fine, as does Mixing Station on Android 8.1, but Qu-You on Android 8.1 won’t connect, just gives ‘Connection failed’. Doesn’t see the Qu-16 on the network and if you put in IP address it makes no difference. Router is DHCP server and wireless connection Ok in all cases. Permissions related?
Qu-16 1.93
Qu-You 1.90 on Android 8.1
Qu-Pad 1.92 on iOS 11.2.2
Mixing Station 0.001.32 (44)
