Errr ok - I’m not being argumentative btw, just Shop app = Shopify, I’m not sure what’s that even explains.
I’ve never used the term Shop app or downloaded “shop app” or “shopify”
I use all sorts of applications at work to help with a varied amount of management tasks, they just perform a function and the end users of my companies products don’t care and will never know. TBH In my role they shouldn’t either but I kinda feel same way about Shopify, don’t tell me it is shit, just get something else that works better, I need no explanation about its failings.
