My iOS and Android apps are working fine for years until recently. I regenerated the keys and it’s giving me the same error.
When I press “Test OAuth” on the website, it says “Invalid auth/bad request (got a 403, expected HTTP/1.1 20X or a redirect)”.
On Android, “Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match”.
