⚠️ Before posting ⚠️

• This is a bug, not a question or an enhancement.
• I've searched for similar issues and didn't find a duplicate.
• I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
• I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

1. Update Nextcloud APP from 3.29.0 to 3.29.3
2. Open random image in app
3. Instead of a big preview, you see small thumbnail, square, and an information on the bottom asking should I download full image?

Expected behaviour

Images should open correctly after you click on it, in big preview, like on version 3.29.0 of the app. Downgrading from 3.29.3 to 3.29.0 fixed the issue.

Actual behaviour

Images open in a small preview after you click on it, in a small thumbnail.

Additional information

Using LineageOS 21, app downloaded straight from github, non-gplay release. Sorry for no android logs, I was annoyed and downgraded immediately.
For the server logs, these are the only one that match the exact time, however they could be not related, because IP given here matches my Home Assistant server, not my phone.

Same here. 3.30 affected too.

Thx for telling this, I just won't update the app until it'll be fixed.
