It's a good app when it works. Connects some days, doesn't connect on others. I stopped to do a forced regen (one of the biggest reasons I purchased the device), the forced regen button, is nowhere to be found. Uninstalled the app, reinstalled it. Still can't find the forced regen button.

Everything worked great, but then came the update today. And now I can't do a forced regen because the start button that comes after the 3 instructional steps is missing. So I start the regen as a result. I tried uninstalling and reinstalling the app, but that didn't work either.

It will clear the codes about 1 in 6 attempts. Reset the app and updated. So far I think I have it down to the Bluetooth priority on the stereo. Still worth every penny. Android on a Pixel 7 Pro.
