Ok, just talking to myself (or to any poor sod who's still reading this forum). Just solved gmail+calendar problem. Apparently google thinks that ye olde nokia N9 mail app is no longer secure and blocked it. So, I had to deactivate my two factor authentication (because who needs that stuff when you only have dickpics and your Swiss bank account details in your email!) and went full Flintstones style to imap/smtp. Works and solves calendar too. Soooo... now I'm rocking gmail with the security equivalent of a thong!
