I understand that there is a solution to this questions although the solution is not working for me.
My steps:
--> Home
--> Teams/<my_organization>/Members
-->Guests (151)
-->Filter by Name
-->remove guest(s) from board(s)
e.g. After I have removed 2 guests, the total guest number reduces to 149...
--> I then refresh the page or click back to the home page...
--> View the guests again and it remains as 151 guests... The guests I removed before have not saved or taken affect.
Is this a bug?? or am I missing a save button somewhere?
