Paypal changed that awhile ago, it all now looks like a mobile display unless you click on 'classic view' in the transaction itself.
It ebay is prompting you to pay for each seller's transaction separately, it could be due to a few different things.
One is that each seller may have listed in a different currency. That has always been a separate checkout per currency.
Another possibility is that your seller(s) selected a setting that says they NOT be paid all at once as part of a multi-seller payment. (That option is there for sellers although I'm not clear on the reason for it.)
Thirdly, it may be a glitch or you might have found sellers who are not-native to ebay.com. The ebay.com Shopping Cart can only handle listings created on ebay.com so if you're looking at something created for sale on ebay.ca or ebay.it or ebay.fr, it cannot be transferred to the US-based cart even when you're logged into ebay.com. You certainly may buy it but you won't be able to combined postage with other items from that seller.
The ebay.ca cart, however, is universal but you have to be logged into ebay.ca to use it. (Come for the cart, stay for our low Canadian dollar.) Like ebay.com, however, the shopping basket on ebay.co.uk is not universal. Remember, you don't accrue ebay bucks on ebay.ca, only ebay.com. Ditto for the Nectar points on ebay.co.uk, whatever those are.
Clear as mud, yes?
