Thanks for posting this! I dont read reddit (or twitter, etc) but normally someone will bring the important stuff here (lol).
I have been waiting for this for a while, as I much prefer paying yearly for this type of thing. I had a little difficulty finding where to do this in the tesla app. For anyone poking around at this like I was, for a few minutes, to change their setting to annually for premium connectivity, try this.
(Tesla app version these steps done on = 4.6.0 -885)
1. Open Tesla app
2. Tap
UPGRADES
3. Tap
MANAGE (next to gear icon)
4. Ensure ACTIVE tab is selected, then Tap
PREMIUM CONNECTIVITY
5. If presented with a billing address screen at this point, verify your billing address and tap
SAVE (I got stuck here for a minute. You wont see billing options until you confirm your billing address if this screen presents itself)
6. Tap to switch to the Annual Plan, and then click
SUBSCRIBE on the resultant screen
See notice that the annual subscription will begin when your current monthly subscription expires (for me, thats March 4th).
Really appreciate you bringing this information here,
@Undisclosed , thanks for sharing!
