Scrivener iOS doesn't work with iOS Files app. (But MacOS do. Weird!)

I have posted this before as a technical question. But perhaps it is more of a bug, why I post it again in this forum.

If I open a PDF in the Files App and make some notes on it with the Pencil and then copy the document to Scrivener or import it from inside a project, the scribbled notes do not turn up in Scrivener iOS. But they are there when i open the same PDF (after having synced with DB) on my Mac. Seems a bit weird to me.

Also, if I open my annotated File PDF in PDF Expert on my iPad, the scribbled notes are there. If I send this (flattened) copy to Scrivener iOS, it shows up annotated in Scrivener, both on iOS and Mac.

Definitely not a deal-breaker, but somewhat of an annoyance. And Weird … Especially the fact that the same PDF, once in Scrivener and synced, looks different on the Mac from what it looks at the iPad.

To summarise:

  1. I open a PDF on my Desktop in the Files app.
  2. I make some note on it with my finger (on the phone) or Pencil (on iPad Pro)
  3. I open it in Scrivener iOS. The note I’ve made is not there.
  4. I sync Scrivener and open the project on my Mac. The note is visible on the Mac — both in Scrivener and in Preview.
  5. I sync the project back to iOS. The note is still not visible in Scrivener iOS.

i.e. the PDF, synced back and forth between iOS and mac looks different depending on if I’m working on my iPad or on my Mac.

Weird, isn’t it?
