It's working fine for me after 1.0B on an Omega DE.
Worked for a few weeks on 1.0A, then stopped working at all. Then worked perfectly after updating to 1.0B.
I'd report your issue here: https://github.com/frederic-mahe/Analogue-Pocket/issues
So the process is this? Does it still work after you restart your Pocket?
Boot the Omega DE like normal. You get a white screen
Save state
Load the state you just saved. You'll still be on a white screen
Quit the Omega DE from the Pocket menu
Load the Omega DE again from the Pocket menu
