2021 R2 Save button not working for lite outlook plugin


With CRM 2021 R2 I am using lite plugin where Save button is not working while you try: Filing an email > Click Add button > Select Regarding > Click Save button is not working. While on same screen Close button works.

I think this is related to some IE setting id some one can help me would be great.
I checked compatibility mode and Java scripting is enabled so far.

Thanks in advance!
