Hi, everytime I open a PDF using collabora office, I switch to other apps, and then switch back to Collabora office, this warning appear. It’s quite annoying. How to turn it off?

Thanks in advance

Hi @Adibuyono ,

Welcome to the forum + thanks for posting. 🙂

> everytime I open a PDF using collabora office, I switch to other apps, and then switch back to Collabora office, this warning appear. It’s quite annoying. How to turn it off?

Yes, I just tested this on my end + it seemed annoying to have to press OK every time as well.

So I submitted this issue to the Collabora Github:

- [Opening PDF + Switching Apps = "Document cannot be saved" Screen · Issue #6774 · CollaboraOnline/online · GitHub](https://github.com/CollaboraOnline/online/issues/6774)

Hopefully it’ll be looked at + fixed soon. 🙂

Can you give a little more info too?

- What operating system are you on? (Android / iOS?)
- What version of Collabora Office are you using?
  - The exact version info from **Help \> About** or the **Three-line menu \> About** helps.

> Thanks in advance

You’re welcome. Thanks for making us aware of it too. 🙂
