High rate of ineligibility on TikTok

This is more anecdotal than anything and I am hoping to confirm with people here. I schedule one post per day to tiktok with Express and often post once or twice a day manually from my phone. 

I have noticed an exceptionally high rate of the videos uploaded via Express are gated and ticktok requires me to request a manual approval, which in most cases is handled fairly quickly. But I do think that if you don't catch it quick enough, losing out on those views during the time you upload to the time when you get the approval, you seem to miss out on a lot. 

So I have a suspicion that ticktok in this case is automatically flagging many of my scheduled posts from Express.

Has anyone noticed anything similar?
