Yeah, I made a Google Photos album to send a link to various potential contractors to show where I want some work done on my house, and since the Photos app for Android has the relevant URI registered, the link gets opened with it instead of just the browser, and the first thing the app does is a very prominent "join" CTA. Then the next person to view the album sees them as a member, gross. It works great incognito though, where the browser doesn't hand off links to any apps regardless of URI registration.
Might try something like this instead.
