The escape screen reopens the link in your own browser, where signing in works.
- On the Almost there... screen, press and hold the button.
- Tap Open Link to reopen the same address in Safari or Chrome.
- If the hold does nothing, select Or copy link manually, then paste the address into your own browser and carry on.
A social app opens links in a browser of its own that does not keep the cookie sign-in hands back, so the login goes round in a circle instead of failing outright. Petboost sends you here rather than into that loop. Once you are in a real browser, add Petboost to your home screen and the problem stops happening.
