Missing Logseq iCloud folder is not recreated on re-install

You really have to store the graph in the folder with the Logseq logo, otherwise the app can’t write anything to disk and you get the errors you mentioned. This is a limitation imposed by Apple.

Try this:

  1. Uninstall Logseq and restart your iOS device.
  2. Install Logseq and restart your iOS device.
  3. Open Logseq, create a new graph and create a folder within the Logseq folder in iCloud (the one with the Logseq logo).
