Error message on mobile devices

Yesterday, trying to get a fresh start with my Logseq installation, with help here, I created a new graph.

Displays normally when I link to it on my MacBook. On my iPhone I get the message below. Additionally, when I go to the pages folder I see only three pages. On the MacBook there are over 90.

Same on IPad, though the directory identifier is different.

What’s going on?
