Microsoft Lists - There was a problem reaching this app
So the solution was to reinstall Teams. I installed it over the existing one (i.e. without uninstalling it first). After that the Lists tab in Teams was working. The clue was that it was working for everybody else except for me (after it had previously worked).
Hi, I had the same problem.
I created a lists tab in the team from an existing list, the title of the tab loads correctly but the content area stills loading the list for a while and finally appears the error "There was a problem reaching this app".
But in my case that error happens to all users of the team, and also in the Teams app and in the browser.
Any idea to solve this error?
Thanks
HugoPires Not sure what you have checked all, but the obvious place to start is with permissions. The original list needs to belong to the same team (SharePoint Group) as where you are attempting to add it as a tab. Else all the users there need to belong to the other team (SharePoint Group) as well, where the list originates from.
Most likely, you already checked the above. More than that I cannot say. Perhaps someone else will chime in?
