neiluj87 · February 4, 2025, 8:18am

Steps to reproduce

Owncloud through browser in mobile (Android/IOS) → Thumbnails are loaded superfast
Owncloud through Windows PC browser → Thumbnails are loaded superfast
Owncloud through owncloud App (Android and IOS) Thumbnails are not reliable, loading slow and sometimes stops loading or take forever. Especially new folders can take ages.

Expected behaviour

Thumbnails (images/videos) should load as fast from the browser as in the app

Actual behaviour

When from the app thumbnails are not reliable, loading slow and sometimes stops loading or take forever. Especially new folders can take ages.

Is there a way to speed up the thumbnail generating / loading for mobile apps?

Is there a way to force the generation of thumbnails maybe?

neiluj · February 4, 2025, 12:19pm

Another thing i noticed is that in the App it seems it loads/generates thumbnails for a while and then it stops.

Is there still no solution to this?

I tried removing the app today after cleaning the apps cache.
Installed the app, added my account and all images started generating when i went into folders, when i had generated all images i closed down the app, locked the screen.

Some time later i opened the app again to upload some images and all thumbnails were gone and no new thumbnails were generating. App Cache was still same size as when everything was downloaded.
