Hi Gary,
Thanks for trying to help out. Here is the main post with different comments from 2017 and 2018 and I thought I had previously found something from 2020 as well but now I can seem to find it again. It looks like you actually even commented on this post as well.
So to clarify a little perhaps, I have not actually double checked in webmail because other email clients are updating the read status just fine so I am assuming that tells me that the Google webmail must be in sync or the other clients would not be able to get that status correct either.
At this point my trial has ended and I don’t plan to pay for a license with this issue not being resolved so, unless they want to renew my trial for another go so I can do some more testing with your suggestions, I’m probably done for now but I do appreciate your thoughts on it. Thank you.
