I miss the ability to view conversion statistics extensively and in one place. With Systeme.io, for example, you have the option to really see the number and percentage of clicks per funnel. You can also filter this by day. Currently, with Plug & Pay, for example, it is not possible to see how many visits there are to a checkout page in a day, so if I want to compare my shopping carts in Meta with the actual number of checkouts, I can't compare that in a good way.

These functionalities include Systeme.io, for example, but also Shopify, for example. More analytics options and in one place are really a must as an advertiser.
