Is this the first print you’ve done with it? Have you done any exposure calibration with this resin?
Ethanol should be fine to use as far as I know. Do the holes go all the way through? If so your screen might have dead spots. You can visually inspect the screen by setting it to do a test exposure without the resin tank on it to check. Also obviously check that your tank doesn’t have any failed print bits stick to the sheet.
It’s not an easy transition. My partner works for DDG and I still don’t use it all the time. To their credit they are working to improve things but it’s a small team (comparatively). Their browser has some good features like app tracking protection just from having it installed and quick throwaway email support but isn’t quite up to Firefox’s standard (yet).
