Wow, I didn't know this...Should have checked when it was last updated but didn't.But, unfortunately, its developer has some personal problems, so he stopped developing. It is not known when he will continue working on Trace.
I went on the developer's GitHub page and here is a snip of his statement. Hopefully, he resumes this soon! OK, so that's a little disappointing. I'm going to disable Trace for now out of caution. Let's see how well AdGuard Desktop does on its own. Thanks again for the info, appreciate it.
