Lesson
Never build anything on someone else infrastructure, if you don't have a watertight contract with them and contact-persons there that can be reached and has to answer to you.
And as for building on top of anything from Google;
Always check out the "support"-forums for it first.
If there are page after page of panicked users whos stuff has broken after Google changed something without telling anyone. And zero helpful response from google. And then those panicked voices just fade out after days and weeks and months of no reply or fixes.
