I’ve been waiting for more than 22 days now for my app submission and until now i am still waiting for a reviewer to get assigned to the app no one even took a look at the app
There is a high number of submissions so delays are to be expected, Shopify have said its roughly around ~30 days currently but that isn’t a promise:
