We're currently having an issue with Pro where when we export a PDF from a map series (either a single page or multiple) and then try and do anything else in the project once they are exported then the project crashes (gets stuck on loading/greyed out options for infinite time). We've also noticed that when reloading a project some layers are always automatically readded to a legend despite being previously turned off/removed.
We've tried to update our Pro, we had a notification for one last Tuesday (24/03/26) but since then we are met which a "Internet connection is currently unavailable" message
