@jpjcandyland Have you tried the normal things like using a different browser or using the app?
If you are using a browser, do you have any plugins or extensions such as ad blockers etc that may be causing interference?
If you are using the app have you checked if there are updates?
Depending on what step you've managed to get up to, are you ordering from more than 10 shops using PayPal? From memory there's some kind of limit like that on a single order but I can't find the help reference now to confirm or deny that.
If problems persist, contact Etsy Support about buying on Etsy: https://help.etsy.com/hc/en-us/requests/new
have you tried doing fewer than 37? I don't know if there is a set limit, but that's the first thing I'd try. Like do 10....
I have heard of there being a limit to the number of items you can buy in one checkout, but I don't remember what it is.
Can you provide a little more info? Are these items from one shop, or multiple?
