Riftgate review for SKU IQ for TikTok Shop or POS

Completely broken. I purchased this app for syncing inventory between TikTok and Shopify but sales on TikTok don't update the inventory in Shopify causing overselling. Our inventory is all out of sync now and we can no longer use TikTok Shop until they fix the issue. I've been told it was "escalated to devs" but it's been like this for weeks now. Crazy that such a crucial feature can be broken for so long. Losing revenue daily and their support team doesn't seem worried about it. Edit: I've now been informed by their support team it will likely take months to fix the issue (the issue being inventory not syncing, the whole purpose of the app). I recommend considering other options before wasting your time.
