This is a bug others see as well,
@CrealityCloud knows about it:
https://www.reddit.com/r/Creality/comments/t8m7p2/creality_cloud_crealityprint_printer_offline_even/

Another bug: the display does not show remaining time, the app does.

Getting there...

Printing now with 3 kg PLA+ spools, so I needed to use a makeshift spool holder.
Printing from SD card, this time the progress monitoring works.

That filalement really made a beautiful print.

I haven't had great results with the Creality Cloud slicer, so I switch to the
PrusaSlicer which is a massive improvement. Clean prints out of the box.

Really love this infill!
