FlySky have released firmware update 1.0.52.1442 09-Feb-2022.
Unfortunately the repeating frames problem has not been addressed.
Here's a fixed version of that firmware. Use FS-I6X_09-Feb-2022_1.0.52_bugfix to flash.
Also included are the original versions of the firmwares from 2017 and 2022 if you want to revert for some reason.
Note that the official
2022updater does not support downgrading. You'll have to first flash the2017version (which does not mind downgrading).
