Clicking open Figma browser tab has 5 second delay

Has anyone else experienced a lag/delay of 3-5 seconds when clicking onto a Figma tab in your browser, before it clicks over to it from the screen/tab you are in (not a loading issue).
And knows the fix?

Tested all major browsers for Mac and it happens across all.

I have tried all the problem solving steps suggested in any topic on here related to Figma being slow and laggy. Browser settings optimised, cache clear, only one Figma browser tab open.

I am a new user so have 3 files and they are small so it’s not a size issue.
