I co own an online retail business called TuffWraps.
Currently we use a main domain [login to view URL] that has its own FB add account, pixel and business model managed by staff in the USA.
WE then use a sub domain of this which is [login to view URL] to run the UK side of the business which also has its own FB add account, pixel and business model run by staff in the UK.
Since ios14 rollout, FB do not support sub domain accounts to operate with their new aggregated event management unless the top level domain is listed on the Public Suffix List.
We are looking for someone who understands the Public Suffix List and can help add our main [login to view URL] domain to it, so we can continue to use a sub domain business model with FB.
