Wrong layout on express checkout

[Nicolasbuch]

Hi there,

I have implemented the paypal express checkout on my website . But i keep getting the wrong layout? 

If i use the paypal clientid, secret and merchant id, provided in their own php examples - downloaded from the official paypal site - i will get the right layout.

Same code base, with my own clientid , secret and merchant id will give me another (old looking) layout. Why is that, and how do i change it?

I assume that it is some account settings. Got screenshots of the issue down below.

New looking checkout (with paypal dummy credentials):

Old looking (my own sandbox credentials):

Can you post an EC token from the old/legacy flow example. Also the debug ID from the API calls please?

Usually the legacy flow fallback occurs when there is something in the account or transaction setup not support yet on the new flow, as its the exact same code, I suspect that you are right in your assumption related to the account.
