Unable to add simple variants

Unable to add simple variants

I am unable to add two simple variants to a product. Support suggested it needs to be added in Inventory first and added to a group (which would mean entirely rebuilding all of my products as I built them in Commerce, which is what I thought it was supposed to allow you to do). Inventory says I have 2 more days on my trial and then it's very expensive. I don't want to use Inventory, I don't need it, I don't want to pay for it and I don't track inventory. I want to add my items in Books or Commerce and be able to add simple variants. Surely this is what Commerce is built to do?

My experience so far with Commerce has been very troubling. Slow support. Tons of issues. I don't believe this product is ready for the marketplace and certainly not worth $60/month in addition to a Zoho One subscription.
