Offline PDF Viewing Not Functioning

[Austin_Nunns]

Hi everyone!
I am attemtping to view pdf documents offline in appsheet. I have them set up as a relative paths for viewing. They are viewed perfectly when online. The files are around 80KB each.

I have read and gone through the following article: https://help.appsheet.com/en/articles/953714-offline-sync-the-essentials

Here is my Sync and offline page:

Any help would be great!

Edit: Forgot to mention I am working with android devices.
Edit 2: I gave the devices each about an hour online with the devices connected to the internet. Alongside that, I opened each file while still online to download the file, then tried going offline and it still didn’t work.
