Why is it not possible on Android to synchronize with the cloud instantly when a file changes, like on a computer? Or is this possible and I don't know about it? I use FolderSync, it works well but it sync my files at scheduled time. Nextcloud synchronize my files as I change them on the computer.

I tried to add my Google Drive account to RCX for some folder sync, but I couldn't. I don't know what is the "Google App Client ID" and secret. There is no information at the documentation page. Edit: I'm so sorry, it's my fault that I didn't read "Leave blank normally" under Google App Client ID and Secret. It worked when I left it blank. Thank you for answers.
