Thanks for the reply, but it doesn’t work. Shouldn’t be this difficult. Using the Mobile Bar has no issue inserting a Photo, but it chokes on a pdf. And the PDFs are there in Attachments and visible to 1Writer and Notebooks3, just not rendered by Obsidian mobile.
SOLVED-
Was NOT enough to turn off PDF plugins (3), NEEDED to DELETE/REMOVE them from Obsidian, restart and all is good -
