Facebook Playable Ad- problem between Cosntruct Releases R268 and R225

Hello guys!

Context:

I developed a Playable Ad for Facebook using R268 and whatever I tried to do the build will just not work. It gave no error on Facebook Preview tool but the demo will only show a black screen. Then I spoke with a colleague who developed another ad earlier this year, but he was using R225 and his Ad worked. So I moved all my assets and events to R225 and it worked for me as well.

Problem:

I presume something happened between releases and Facebook doesn't like it. Any idea what could have gone wrong?

Thank you!
