Nextcloud iOS app photo cache problem

The Nextcloud iOS app caches all photo thumbnails when browsing the Media (Photos) page, which takes up a lot of storage space on the phone. Is there a way to change this behavior so that photos are viewed online, like other cloud storage services, instead of being cached locally?

I have 600G photos. All photos about my life. So I really want to browse them on nextcloud iOS app. But my phone does not have enough space to cache all photos thumbnails in media page. So said.

In the advanced settings, you can see the cache size and also delete files from cache (via date). What is the size of the cache used?

Cannot set cache size. Only can set when to delete caches. See more photos in media page. The caches will grow up…. So I cannot browse more photos right now. Caches so big

and deleting things older than … does not help?

How big?

100GB,browse more let caches great again,

delete caches. When I want to look through the previous photos (but I don’t know the specific time). I can only continue to slide down to find the photos. There will be more and more caches in the process.

delete caches older than xxx(if x is 7day) is useless. This option will delete caches downloaded 7 days ago
