Add-ins on microsoft word

[Azra10]

Hello, 

I am unable to insert add-ins on my Microsoft word. I get signed out of the Office add-ins page after I purchase the add-in on the Microsoft office app-store. I am using Word version 16.64 on my Macbook. 

Thank you.

This issue persists even if I tried to add multiple different add-ins and also when I tried add-ins on excel and powerpoint.
