Why some channels say "in platform review"

Instagram, Facebook, TikTok, and LinkedIn are publishing today through a provider that already holds the platform approvals. YouTube and YouTube Shorts are waiting on Google's OAuth verification. Until it clears, those two stage as notification posts: Dubb Social hands you the file and the caption, you confirm the last tap in the YouTube app. Nothing silently fails.
