Blogger Pop-up code not working anymore


Has blogger stop support for pop-ups ? As of today 14/3/16 I got yet again another nasty blogger surprise when i found out my pop-up code stop working in my posts. Don’t know why they keep doing these things! blogger is becoming one of the most unpredictable & nasty blog platforms, If it was not for the fact i 3000 posts i would have left tinkering blogger ages ago. does anyone have a solution the pop-up code that just stopped working or the best way to move my entire blog away blogger to a more reliable one with no continuous nasty surprise?
