They should add verification within the app store. I’m sure there’s a review process before apps are allowed in the store, but I usually avoid installing apps on my Umbrel unless they’re submitted by Umbrel or the original developers. If it’s not submitted by Umbrel or I don’t recognize the name, I typically don’t install it. There should be a clear way to get verified and this would allow people to know the app is fully authentic at a glace.
