## Summary

Good morning. I would like to report an issue we are currently experiencing when using tablets with a Kolibri server (version 0.18.0). When a PDF is assigned as a lesson, if it has more than two pages, we are unable to scroll to view the remaining pages; the screen only allows for side-to-side movement. I am unsure what might be causing this and would appreciate your assistance.  
We also tested this using a mobile phone and encountered the same problem; it only worked correctly on a laptop.

Our current setup is:  
Windows 11  
Kolibri Server Version 0.18.0  
Tablets running Android v. 12  
I have attached a video of the issue for your review.

## Technical details

- Kolibri version 0.18.0

- Operating system Windows 11

- Browser Chrome

Thanks very much!

I have a quite a number of pdf files to upload into Studio - should I wait for the fix or I can upload them now?

Will keep on checking.

@nyasham60 This issue is displaying locally once the channel is imported in Kolibri, not on Studio.

So yes, you can upload the PDF resources in your channels on Studio, publish and even import into Kolibri. The rest of the resources in the channel are not affected, but the PDF files will exhibit the behavior described in the initial post, until the issue is corrected in Kolibri, and the new version is released and installed on your devices.
