Sadly

Note – when people write that this plugin creates junk in the database, that’s what they mean. I was skeptical at first)
In general, read the reviews – a lot will become clear.
Look at running sites (services like “themesinfo” will help you find them). Personally, after looking at a few, I saw the form “always loading”. Is not very good for users. Although personally I have not encountered this problem
The registration process is just infuriating!
Here in the reviews, here in support, on the support forum of the official site, the same question!
Why did you separate the registration process? You answer that in those distant times, someone asked you about it.
Do you realize that this drastically limits the use of your plugin?
Let’s exclude the one page site with the order form – yes, it works.
But this does not work where it is necessary to have user accounts.
For example:
… Hairdresser / Beauty and cosmetology – I might want to sell related products (perfumes, accessories …) – no! Two different entrances!
… Holiday service – Maybe I want to order food / drinks, festive paraphernalia – no! Two different entrances!
Yes, any website with goods is faced with a problem. What if it’s a running business with a customer base? Ask them to register another account?
Additionally:
Any site with a subscription
Selling courses
User support
Sites with user content
Membership
All sites with user accounts! What is the advantage of your approach to registration is completely incomprehensible!
