Do you mean the pivot bolt is coming loose?
I had that on my stage 6 for a while when the soft bolt head started to round out and I couldn’t torque it up enough.
If that might be the case here, then in the short term I’d suggest grabbing a spare brake mounting bolt and whacking that in instead, to see if it cures things.
I believe I contacted Orange about purchasing new bolts and they posted me some free. But the brake bolt would have been fine forever TBH.
On a side note, I was riding some fast, twisty off camber trails when the problem emerged and the extra flex between front and rear felt amazing – and allowed me some Strava heroics.
