> So unless I switch to the >=EUR6.00/month Plus plan I cannot add a non admin user? So my grandma gets admin privileges? Is that not a blocker for a lot of families?
Maybe, but at least it's not per-user, per-month. I'm much more likely to set up something like this if I can add / remove family members as needed without thinking about the cost beyond the annual fee I pay for to run my own instance.
The blocker for me is typically ease of use. They recommend PhotoSync for transferring files to the instance. I currently use that for my family, but sync to a Nextcloud install (which I desperately want to replace). The part where it fails for me is that my family members don't understand how to verify everything is running as intended. For example, I checked one of their phones earlier this year and they had 5k un-synced photos.
What this really needs to be useful is a native app that does sync from the phone in a way that makes it relatively foolproof.
Beyond the ease of use, every link in the chain of the workflow is a point of risk IMO. For example, what if PhotoSync rug pulls everyone (I have no reason to believe they would) and starts charging a subscription? The app that runs on your phone and does the syncing is the more valuable half of the workflow IMO.
