Simply Shady Designs review for TikTok

Great when it works. Pulls order into Shopify where I can fulfill the order and adds customer to my Shopify Customers list which is great! Can run campaigns for promos and TikTok offers many campaigns that help boost my sales. Been using it 3 months. BUT, the past week all of a sudden none of my TikTok orders pull through to Shopify like they are supposed to where I fulfill the orders. I have reached out to TikTok support on 5 different occasions and never got 1 response.
