Similar situation with VS 2019 GIT using Axure Dev OPs as the remote repository. Any suggestions are welcome!

1 everything is fully synced between local and remote

2 I open a file from solution explorer. As soon as I make a change, the red checkmark correctly appears next to the file in Solution explorer. However, as soon as I SAVE the file, the checkbox disappears, and if I try to commit there are no files to commit!

I have cloned the repository many times and this keeps happening.

3 My workaround is to make my edits and save. Yes there is no red checkmark. Then I reopen file again, make a minor change like adding a space. WITHOUT SAVING, I commit, and the changes are now all captured in the git changes window. After PUSHING to the remote, I see all the changes on the remote's history and the local gits history.
