I installed this app and paid for the premium version with support. The only support option is to email within the app, and all I get is "email cannot be sent"

Super frustrating.

The app was not working properly, and didn't remove the buy now button. It just shows both pre-order and buy now buttons next to each other.

we involved Shopify but the problem didn't resolve and we had many frustrated customers and tens of complaints.

Really bad experience!!

The app worked well for a few days.
Then their server seems to have stopped working. My site is totally blocked (it load a page in 55 seconds).

The app is very buggy. Also reached out for support and gave them over a week to answer with nothing to show for it aside from some money out of my bank account. At this point I'm uninstalling and going to a different option.
