Definition of tracking problems Quest Pro Controllers

Hey, been spending time on this excellent forum trying to make heads or tails of what my tracking problem actually is. I am deathly afraid of making a mistake and bricking my controllers (again) since I am now out of warranty and I get that if you update-brick your controller support now tells you to f off end get a Q3.

So here is my problem:
The Quest Pro controllers are visible in passthrough but they are not correctly placed. Instead the virtual controllers are about 15 cm to the left and right, respectively. This has more or less always been the case, but the controllers used to snap into position once they've gotten their bearings after a few seconds. This is now no longer the case. In apps like Horizon Worlds the controllers then do not work at all.

Possible solutions according to Meta:
- Restart controllers
- Restart headset
- Re-pair controllers

Tried all that, no joy.

Possible solutions according to this forum:
- Upgrade to PTC 71 version 2 (apparently version 1 made everything worse) - I am a bit afraid to do this - seems not heeding the warnings from Meta on unsupported updates is very foolhardy when they no longer want to support the Quest Pro in any way.

My question is: Is this particular problem (controllers visible but not aligned) known? Am I correct in listing the workarounds or are there more/others? What possessed me to get a Quest Pro on launch day?

Thankful for any input
