I’ve restarted both my Mac and iPhone before further testing, but the same problem.
I only stated making scans in the last few weeks. I’ve found one scan that does open, but I can’t see what’s different about it. The rest don’t open.
Also, I’ve now discoverd that when I drag them to emails as attachments, they are added to the email, but when I go to my sent emails, and try to open the attachments, I get the same error message. (I’ve not heard from any recipients that they can’t open them)
I have now experimented with scanning (on iPhone) into a note that already exists on the Mac, a newly created note on the iPhone, typing into the note before and also after making a scan, no typing at all. I still get the same error.
I’ve tried closing Agenda on the Mac while scanning, then waiting 10 minutes before opening Agenda on the Mac. Same error.
I’ve tried to find a scan in the Finder. I searched on the name I’d given a scan in Agenda, and found the pdf - I can open this pdf. (The same scan is also found in my sent folder for Spark email in the Finder - but there it has the name I gave the scan in Agenda. I can also open these scans.)
I also found the same scan by searching on a word that is in the scan, but not in the name I gave the scan. It seems the scans have been OCR’ed.
OK, this is getting weirder. It seems to be a Mac problem, not an Agenda problem:
When I navigate to pdf document on the web in Safari, and right click to open the pdf directly from the browser window, I get the same error message. But if I download the pdf to my downloads folder, I can open it with no problem.
