eReader in Zotero app on Android no longer working

0bi0n3 · 2026-01-15T10:12:20+00:00

Since a zotero app update in December, my Lenovo Tab M11 running Android v15 has stopped loading PDFs in the eReader.

Tried uninstalling/reinstalling app, resyncing with WebDAV but still just has a loading circle indefinitely.

Debug ID = D2107218965.

Anyone else experiencing this?

Are you experiencing this issue with all of your PDF files or just a small subset?
What is the file size and page count of PDF's you having problems with?
Can you please post a screenshot of the screen on which you see the infinite loading?
Is the loading circle spinning or is it just frozen stuck?

Thanks for replying.

It is happening on all PDFs and now when attempting to highlight it often crashes.

Mainly spinning circle but if loaded and highlighting / annotation taking place it completely freezes and asks for the app to be closed.

Here are the three stages:

- long loading hang time. If it passes loading, which is occasionally within < 5 seconds, the next bug occurs. Approximately 50-70% it indefinitely loads.
- if it loads, highlighting is sentence long on selection and then hangs for approximately 10-20 seconds.
- 90% once highlighting has been activated it crashes after the 10-20 second hang time.

I have refreshed, updated and reinstall the app. Android version 15 on Lenovo Tab M11 as detailed above.
