Hi there! I use SET as well. I usually check to see if I received any activity in the individual programs within the SET funnel.
For example, in the freebitcoin one, you can go in there and check under "refer" tab, scroll all the way down & see if you have referrals and their earnings. You can do the same for Presearch.
With HIVE, you can check for initial sign ups under the wallet transactions.
The only one I am not certain about is the Brave Browser. lol
Unfortunately, there is no single place to look at for all referrals in all programs. But who knows? Maybe that will be something they will add later on down the line.
I hope this helps a bit. :)
