The update has now been pulled for both Z fold and z flip.
With every update, and especially with such a big redesign, I always undo all personalization before update and restore the original theme that the phone came with. I read that a long, long time ago on the xda forum, advice on how to avoid unexpected errors. And since I've been sticking to that rule, I've never had any problems with the update, nor have I had to reset the phone to factory settings. After the update, it takes me a few minutes to personalize the phone again And that's it
