I have tried it all and so far, no success.
I have updated my iPad Pro to its latest version (15.2) - Obsidian 1.0.5 latest available.
Since then, despite deactivating, restarting and even completely removing plugins - I went as far as to create new/fresh/empty vaults without even so much as touching the settings - I can no longer have PDFs displaying on the iPad.
All of a sudden, Obsidian rendered itself useless to me, since my workflow primarily involves PDFs.
Any help would be GREATLY appreciated.
** I do not wish to go back to Obsidian’s competitors, but sadly I would have to unless I am able visualise these files. :[ **
Best cheers and greetings from New Zealand.
