They seem to have started to redirect to web login page which doesn't exist yet so it redirects to homepage when you "power use".

I noticed it's becoming unbrowsable on my VPN where other IP users probably use up all of the "free view" tokens for the shared IP address. I guess that's one way for Meta to have their cake and eat it too.

There are read-only web links for users and posts. The easiest way to see it is by copying a link to a user or post from within the app. But there doesn't seem to be a web landing/browse/feed page yet (besides the main page that just gives a QR code linking to the app).

On top of that, when you download the app there's only an option to login with instagram. If you don't have an instagram account already there's no link to create an account. Surprisingly inconvenient.
