Tapcart ‑ Mobile App Builder

Design is great and price is very affordable, but the app has some obvious overlooks and really buggy. Customer has to add payment every time they checkout even though they are signed into their account and items that do not require shipping (digital downloads) won't let users complete purchase because it wants a shipping method to be added. The latest update has some nice additions (showing product reviews and design features) but really wish these other items would be considered and fixed.
