I created a umap, and wanted to test the realtime collaboration feature. Switched it on, and a tab appears showing my name.
Then I went on holidays and used my other laptop there, tried to use the umap, and I only get 3 edit options (draw marker, draw polyline, draw polygon) and cannot edit anything. The collaboration tab shows “disconnected”.
When I disable the collaboration (after my holidays when I got back to my other PC), the page on both PC work fine.
I also tested by opening the same umap in a private browsing: same issue. It shows “disconnected” and very limited editing possibilities.
