I’ve been using Creality Print on my K1 Max for over a year with the Android app with no problems. A few months ago, with no updates (that I know of), the video doesn’t work. I have to hit re-try several times after timeouts. Sometimes, it doesn’t work at all. I’ve tried uninstalling and re-installing the app. Nothing helps.
Does it work via the browser (enter the IP, make sure that you use http:// in front of it not https:// and that you are in the same wifi as the printer) or Creality Print 7 on a computer?
