No Access to vault via iOS file app

Using a new iPad, I can’t access my vault using the File app.
As the symptom is pretty commun, I eliminated the know causes to no avail :

  • the (cyphered) data are present in the iCloud file
  • the vault was sucessfully unlocked and added in the Cryptomator app (in opening the d file which includes a masterkey and a backup)
  • the crpytomator file is visible in the File app (but not it’s content)
  • I deleted and reinstalled the Cryptomator app
  • I (force) retarded the iPad
  • I have access to the data from my iPhone and my Mac

Thanks for your help

Inspired by other posts, I succeeded in forcing the FULL download of the data in the iCloud Drive on the File app
