Blanka Makeup Beauty Cosmetics

Installed the app today on brand new shopify store and it doesn’t work. Trying to publish to store, blanka gives a success message saying the product has been published but the spinner keeps rotating for a minute before giving up. All other non-blanka apps work perfectly fine with my store. Also, no support available after 6 pm and night, I have to wait until tomorrow morning Canada time for them to wake up and look into this issue. Very very disappointed!
