On my main user profile I currently have Aurora store, Fdroid, and Obtainium all running. Some of the apps I've installed show up in all three stores even though I only installed them through one (for example: I installed Proton VPN through Obtainium, but it is listed in all three of my app stores under my installed apps).
Is this expected behavior, or will it cause problems, say, if all 3 app stores try to update Proton VPN?
