Hi, Dear Folks,
Tested 1.3.00.21759 on an (updated as possible) W7.
Go to the settings->General tab.
1) The "Save and Restart" button appears only if I change the status of the "Enable spell check" option.
2) Also if I disable all the checks, once exited from teams and restarted the PC, "Enable spell check" & "Turn on new meeting experience" appears again checked.
