Domain verification Flippa for 126 domain cryptographic portfolio

Hello,
Has anyone else had problems obtaining verified domains using flippa?
Finally I managed to configure my list of 126 premium domains related to Cardano / ADA, but it took me more than 20 messages with its support before it was correctly configured.
