Preemptively putting this here. Tiktok stores is going to be a thing very soon. (Tiktok(douyin) stores is huge in China for the past 2 years, the concept is a proven one and they are in the process of testing this over at the Tiktok version).
Facebook/Meta also mentioned they will have heavier integrations with in-app stores.
MMIO should get in ahead of the pack and be prepared.
