Yeppo® review for SS: Product Expiration Dates

The app have lot of bugs and we had to be the QA of this app to let them know of the problems they have or functions that must be added to the app. For example, this is not compatible with orders that are placed for store pickup (native function of Shopify) as stock is discounted using the main warehouse of the e-commerce and not from the branch. Something basic. I tried to book a call with support team, because writing English was not good and did not understand what they were saying, but devs or support team kept writing me in a illegible English.
