Quick summay of my experience with LSP Android version (Pixel 4a) on a 2021 SL+ using newly purchased LELink dongle:
App connects most of the time but not always, not sure why.
Data is way more than I will ever understand but nice to have.
Service screen works well for changing door lock, headlight, and interior lights defaults.
Not tried resetting any fault codes since I do not have any.
VSP settings will change for a few seconds, but then revert to factory settings after the 'countdown'.
I cannot get them to 'stick'. Any suggestions on how to make VSP changes permanent would be appreciated.
Just occurs to me - should I hit 'DONE' while countdown is in progress? That button is not active after countdown.
