ColorOS 13/OxygenOS 13 experience?

[Miquest]

Hi,
I have an Oppo Find X5 Pro with ColorOS 12. With a few workarounds, xDrip Plus is running perfectly.
But the ColorOS 13 rollout started a few weeks ago and I want to upgrade as soon as possible. Has anyone experience with ColorOS 13/OxygenOS 13 (now almost the same) and xDrip Plus or the Dexcom BYODA App?
I will not be able to downgrade, I have to send my phone to an Oppo Service Center, so I want to be sure that it is working on my phone before I install ColorOS 13.

Kind Regards,
Thorin

Nobody?
Are there no Oppo and OnePlus users?

Are there no OnePlus 10 Pro Users in the US or Find X5 users?
I need your experience, because I don't want to give my Blood Sugar System away to reset it to Android 12.
