Have you considered pulling out the Immich update notification from the release? Or at the very least, posting announcements in-app an pinned on the forum about the issue, what users should be doing, what is your plan.
I have had to scan multiple threads and posts to come to the conclusion that I should probably just wait, not try to update Immich, and that you might be sorting this out in a future release.
What I know from the team is that you are working on the issue, it's not your fault, but no guidance π
