Join Shared Board/List Message Keeps Popping-up#1546

When logging into Tasksboard a “Join Shared Board” message continues to pop-up even though the user has already joined the board. Also, I have another user that is getting an empty/blank “shared list” message with a spinning loader icon after I deleted a list that I shared with that user. NOTE: in both instances we can still close the message or click off to access the Big Boards but this message pop-up reminder happens everytime we access Taskboard daily.
