i’m not sure I know what you mean, the payment system was always that you get paid after they have sent it to the buyer, usually the same day or one day after it passes inspection, if you got the expert badge you must have had at least 5 successful sales in the last 6 months and know how it works. Their payment system isn’t new, I seem to remember that a few years ago they paid every 2 weeks and their wallet was for keeping money from sales in sort of a virtual wallet, that you could then use for purchasing items. I always preferred to pay with a CC, just in case something went wrong.
Compared to how it used to work, it’s pretty fast, I don’t recall that they ever paid immediately, there was always payment on a certain day of the week, understandable because it makes the admin easier. I’m just totally confused where that’s new. The wallet was phased out quite a while ago, possibly for security reasons? I’m not aware that they ever paid immediately.
The badge just shows buyers that you sell a lot and are a reliable seller, it has nothing to do with payments, since you got the badge, this really shouldn’t be new to you.
