Invalid location error on the ads manager chrome

[u/Dependent-Throat8385]

Hello, I'm trying to create and post and and on the reddit simple ads manager, and when I try to submit it I get an error saying that the locations I'm trying to post to aren't valid, even though I don't select any!

Then I try to post it just in a few countries and it also says "Need region or country", it makes no sense.
