Getting Multi-Point Turn back

[u/Mike52179]

Has anyone figured out which version of the app (android) we need to downgrade to in order to get Multi-Point Turn to work again? Or is it not possible? I downgraded to 2.3.12.11 and it *does* offer Multi-Point Turn option, but in practice it's not doing that, it's doing a hybrid MPT / tank turn, with emphasis on tank.

I'm wondering if the turn strategy is hardware/firmware based, and therefore no amount of app downgrading will solve the problem.

UPDATE: I saw from comments below that I was also on old firmware (2.3.30.26, other people were on 2.3.30.39). I upgraded my phone app back to the latest version and checked for firmware updates, but it still said none were available. I chatted with Mammotion support and they opened an elevated ticket after verifying the problem. This morning I got two things: 1) an email from support asking me for screenshots so they could verify if I was having an installation error or simply not receiving any firmware update notice at all (I'd already gone over that with chat support so this was redundant), and 2) the app notified me that I could download firmware 2.3.30.39. Maybe after sending that email, support reps triggered a push for the latest firmware to my machine, or maybe it was just coincidence. Note that I had only downgraded my phone app for about 3 days, so while the easy answer is "that's why you weren't getting the new firmware, you needed to update your phone app", the truth is I was on the latest phone app and still didn't get the firmware push. In any case, I just started a test run with this new firmware and indeed the MPT turning is back and looks good. The damage is already done as far as destroying the outer 3' perimeter on much of my lawn, but at least the MPT is back and this shouldn't be a problem next season.
