As I try to transfer my product to Magento 2.2.3
I face 2 issues
!) my customer cannot upload an image through Magento to my email account
2) as I apply PayPal to check out cust cannot apply the term and condition to redirect to PayPal
@JewelryNest - From where you are going to upload images ? I have sign up and see in my account as a customer there is no option to upload image at front side so.
For second question - as you are using paypal express checkout - so from cart page it will directly goes to paypal payment screen as its a there option.
still elaborate more on the issue so it helps us to troubleshoot more.
