... I just didn't realize that something with a premium price tag would be so limited in function. ...
For what it is, it's functionality is not limited at all. The FPV and Mavic products including the Mini are quite a bit different when it comes to target market.
Sorry you do not like it. I'll ask one more time if you'd like to share your flight logs to see if the good folks here would be willing to troubleshoot the issues you had, but it doesn't seem like you're interested.
My suggestion - sell it.
