I have an a1 mini, and I do not have AMSLite, so I swap colors manually. It works fine until lately. Lately if I have a pause and I unload the filament, it unloads then it gets stuck on that screen and I can't load another filament. I have to cancel the whole print. Its incredibly frustrating.
I have re-installed bambu studio, update firmware, done a factory reset and a whole slew of other things.
