nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg bookmarks on iOS of last 5 days disappeared or are not available

I wait some days

and will check later what the desktop version has

I like to bookmark alot; last days I noticed the new added bookmarks didn’t show sometimes/disappeared a little later when scrolling and returning to the bookmarked post or see a repost (I mean the blue fill of the bookmark icon in the post itself);

is it a storage problem maybe, because too many bookmarks?
