Too many master keys slowing down iOS/iPadOS app startup tremendously

Operating system

iOS

Joplin version

13.0.7

Desktop version info

No response

Current behaviour

Starting Joplin on iPhone or iPad it only shows a white screen for about ten seconds. Then the notes show up.

That is much too long to make it viable for quick notes.

It turns out (from the logs) that Joplin is loading 14 master keys, in about ten seconds. All of that long startup is just key management.

I haven't found a way to get rid of the keys. I can deactivate them on Desktop, but not on iOS. I then re-encrypted on Desktop Joplin and synchronized to the iOS devices, they just added all the keys back, it seems.

Four or five master keys per device. Shouldn't it be one key per device, after re-encryption?

How do I expunge the old keys?

Expected behaviour

Open up within a second or so.
