Attachment Limit - New Board

[Danielle]

in June 2025 we had the pop-up of reaching our limit on number of attachments on a board (after using since 2018!)

I wasn't able to delete any old archieved cards, so have created a new board to use instead. The issue is, every now and then the new board pops up with the same warning of number of attachments which isn't the case. It stops my teams from uploading onto cards for a day or two, and then suddenly it's working again. 

Any advise on how to manage this?
