They have stated multiple times they are working on it. Some of the issues are on SiLabs' legacy code (which is no longer being updated...), and not Hubitat's, so there is only so much they can do on their own.
They know about it, have made it much better/more rare for most users, and are continuing to try and improve it best they can.
There is no ETA on when (or even "if") it will be 100% fixed. That's the best answer you are likely to get at this time.
