I have a basic Trello board that my wife & I use for shopping lists, packing lists etc.
I also had a separate board which I shared with a bunch of neighbours & gave access to about 17 people.
I recently fell foul of the 10 person limit so I went to the board where I gave people access & deleted most of them.
The features should now work, but the shopping list board won’t work.
I have uninstalled & reinstalled the app, tried hard refreshes, logged out & in, selected “clear cache on launch”.
Whatever I do, I can’t get it to sync to the changes my wife has made to it. I’m pretty sure the syncs stopped as a result of too many guests on the other board, as I was getting notifications about it. The notifications have stopped, but the functionality hasn’t returned.
