Affects all browser based API's bots ONLY, not ANDROID APP based bots. The SOLUTION for all BROWSER based bots is to remove the USER AGENT for a quick fix and then to add cookie support going forward.
Followeliker is emulating Android, no? And it has the same problems.
Also just tried what you posted (using the web api from code, but without user agent) and it made no difference, the same response - checkpoint required, etc.
