Thank you. I believe I may not be explaining this properly as I am not a developer. The folks from Aero replied to me as follows:
Slightly confused now.
Enabling a cart icon on top header has no relation to using (or not using Aero).
Now in current state (Aero is not active),users are still not able to navigate freely like they would on a shop and decide at will when to checkout.
For instance if I land on Product A and fill up details and do add to cart , there comes a message on top which proceed to checkout. But if move to another page using navigation. and decide to proceed to checkout I am lost.
Aero would come into play once user reaches checkout. Which is when it shows
1) Custom templates
2) Can do multi step checkout flow
3) Add Custom fields etc
4) Add social proof and other conversion triggers to thwart Cart Abandonment
5) Add Order Bumps to increase average order value
So Aero would work once user reaches checkout.
If you can shed insight, that would be so very appreciated.
Thank you so much.
