some of my maps that are nearly a year old also won't load even at 1k resolution, some of my other maps would load but assets would be missing, or I would get a black screen.

This definitely needs an immediate fix so we can get back to our older maps.

The 2.0 update literally either broke my older maps or made them not load at all

been having the same issue, they'll load with no background, sometimes with assets/stamps, sometimes without. also considering cancelling.

Same issue, I click "Edit Map" and the loader gets stuck at 100%

Exact same issue here. But it's only with specific maps for me that have no common denominator so far.

I should also note it's not a matter of asset density, as some of my world-maps load just fine with 1000+ items, meanwhile some of my local maps with at most 100 do not load.

Could be an issue caused by the upcoming 2.0 update?

I'm having the exact same issue, its been persisting for over 2 weeks. I am highly considering cancelling and never coming back if this isnt fixed.

I am as well. I haven't seen any action on this.

Still having this issue. Considering canceling.
