Oh, and here I was thinking it was because I has multiple browser tabs open! Our company product is based on Stripe Connect, so I spend a good deal of time on the Stripe Dashboard. I can't for the life of me figure out why it takes ~15 seconds to switch from the Products tab to the Coupons tab, all of which have about 20 records! They have great API's for sure, but their skill on the front end leaves a lot to be desired.
You can use Dodo Payments for Payments. I have personally used it in my project https://sololaunches.com
