How did you improve the ground system? Added some bonding straps? Could you share some info on this? Maybe pictures? I'm thinking about adding some too.
I would check the canbus wire harness. Look for broken wires, inspect (visual inspection) the connectors for broken contact pins, bent pins, corroded etc. Do a pull test: gently pull the wires at the back of the connectors to see if any wire is broken or it's coming out of the connector. Look...
OK, checked it today again. It's a lot simpler than you think.

Go on an official Mazda parts website. Have your VIN number ready and look for that mirror and check it against your VIN number. Better yet, go to your local Mazda dealership at the parts department and ask them to find your mirror part number.
You have to drive the car 62 miles or 100 Km before it pairs with the VIN number. Which I think it's the case here, since the gentleman says in his original post that he drove the car for 3 months. So, I believe that it's not possible to update this SD card in the future, if you are using it...
From a warranty perspective, my dealership had no issue with 5W-30 when I brought in my own oil, on my old 2020 CX-5 NA. In my case, at least, it did not void any warranty.
