FYI this has been resolved in 26.3 RC.

@poirotsj it's still open, and no one has reached out to me. Considering it's happening to (at least) a few of us, I'd recommend using an alternative approach.

@DTS Engineer I submitted feedback a week ago but haven't heard anything. Should I expect a response? At this point, I can't enable CloudKit. I'd be happy to implement a workaround in the near term if one's available.

Thanks Ziqiao, I just did: FB21576369
