You can either make them part of the build having Unity put them there for you. Or you can also just upload a zip yourself using the FB developer backend site.
On then I misread your post, sorry. This is an issue on FB’s side so you have to inquire about it on their developers forum. There were no changes to things on our end.
I’m seeing the same. I noticed on a FB Instants group that FB are refusing builds which don’t contain the “official” FB SDK. Perhaps they don’t consider the Unity FB SDK to be official?
Actually i just want to upload game on Facebook Gameroom. But for In-App purchase, I have to have include “Instant game”. Its is really very confusing for me. and when i try to upload build on that i got same issue.
also i wants to know, Can i use IAP(Unity’s) without adding “Instant game”?
I wanted to experiment FB instant game and ended up with with the same issue, I’ve found this thread, though not tried yet HTML5 Game Devs Forum - HTML5GameDevs.com
