Unable to view PDFs that have been scanned with an OCR scanner app.

As per title. PDFs show up as blank if they have been scanned in with an OCR scanner app then saved.

Bei mir funktioniert es wenn ich die PDFs mit 200 x 200 dpi gescannt habe. Bei 300 x 300 dpi geht es nicht.

It works for me when I scan the PDFs at 200 x 200 dpi. It doesn't work at 300 x 300 dpi.

I'm having the same problem. The scanned PDFs are visible on Windows and macOS, but not on iOS. However, I tried scanning with a different device just now, and it worked. I usually use a sheet-fed scanner (Brother ADS-2800W), but it doesn’t work with that device. It does work with my all-in-one printer (Brother DCP-L3560CDW). All devices have the latest software version. Maybe this will help with troubleshooting. *** Translated with www.DeepL.com/Translator (free version) ***

Same issue with uploaded PDF files in iOS App. PDF shows a blank white page. On Mac or Web PDFs shows correctly.

Same issue with a four-page scan of handwritten notes. Used Adobe Scan on iOS device to make PDF. PDF previews are viewable in other apps (Acrobat, Evernote, and Obsidian). PDF previews also viewable on Capacities MacOS app.
