Scenario: We let a small group (5-6 people) work simultaneously on one single, basic mind map. They learn to use the map, adding some branches and siblings from scratch.
Maps seem to work regularly before and during this phase.
After that, each member of the group is requested to work on his or her own mind map. 5-6 different mind maps updated simultaneously.
It erratically happens that, after creating a new map element, whatever the command (mouse or keyboard behave the same), the new element immediately disappears.
A workaround is to insist. After some trying, usually the new element is created and stays. It can happen or not; I counted even 19 tries on a single node, while others nodes worked regularly. When the bug shows up, it is usually necessary to try about four-five times before the map correctly responds. Maybe that several nodes work well in the meantime, then the bug shows up again.
Trying new fresh mind maps doesn’t help.
Duplicating the board doesn’t help.
All users on the map can be affected.
We see the bug in the up-to-date Mac app and on Windows in the browser (Edge, Chrome, Firefox). Different platforms seem not to affect the situation.
