I recently moved to Nextcloud and so far the experience has been great! Migrated documents from Google Drive to NC instance already and now in the process of transferring photos from Google Photos. What I love about the Google Photos apps is its ability to automatically sync photos and at the same time resize/compress the images.
Although the Nextcloud android app does pretty well in auto sync’ing but I do feel it is missing the latter part i.e. image compression. Is this something the developers are considering for future releases or has this feature been left out deliberately.
