Without a Makerworld account you won’t get a support ticket. As long as I am not logged in with an app, there will be no update messages on the printer as well as you can`t get them at all and you can not deleat any maintenance steps as well…
Even if you use your link, you get this:
Markerworld is mandatory for Bambulab printers - I will by more than happy to be corrected on that point.
