Magisk Canary was updated to
23016 last night. This includes a
fix for the vbmeta header issue, meaning that disabling verity/verification should no longer be required, and we should be able to root as we did before.
This needs testing, make sure you back up your data and photos before you try this!
Q: "If verity/verification are disabled, do I need to enable them now?"
A:
No. The only thing you have to do is update to Magisk 23016.
Q: "Will enabling verity/verification wipe my data?"
A:
No.
I will be updating the OP to reflect this.
