Hi!
I agree with topic starter. My machine always looses WiFi. I mean cloud is not working properly. I have UM3 on latest firmware, cura 4.8, macOS Big Sur.
Cura can see the printer, but sending print job is doing nothing.
it was better before latest firmware update, I was able to print via WiFi. Now I have only cloud button and it often doesn’t work.
As I see, it’s not only my machine.
what can we do? (Expect switching to Prusa, they will have cloud soon or already have)
