Common errors with 4strokemedia.com lines
-
Seller type BOTH
21 lines
The account is listed as BOTH, so sellers.json alone cannot tell a buyer which relationship applies. Nothing to fix on your side; buyers usually look at the seller's domain.
-
Confidential seller
9 lines
The seller is confidential in sellers.json: its name and domain are hidden, so buyers cannot confirm who it is.
-
Seller ID not found
1 line
Ask 4strokemedia.com for the account ID it lists for you in its sellers.json, correct the line, or remove it if you no longer work with them. Buyers that check sellers.json drop these paths.

What is the certification authority ID for 4strokemedia.com?
100% of the app-ads.txt lines naming 4strokemedia.com carry "ef9e7658006e9654" in the fourth field. The field is optional; the IAB Tech Lab ads.txt 1.1 specification says identifiers in sellers.json supersede it, so a missing or different value does not make a line invalid.
