Used ironvest for many years but masked cards are still not active. I use the privacy free plan which allows 12 new masked cards per month and Proton Duo for masked emails. I started using privacy when ironvest stopped mask emails. They have been saying the update is coming soon for a full year now. My experience with Privacy has been very good. I have never needed more than 12 new cards per month and currently have about 25 active masked cards I use regularly. You can make the card merchant specific or one time use with customizable limits. I use a privacy card with my iptv service with no issues. Occasionally, some masked cards are rejected but those are usually well known reputable businesses. In that case, I use bitcoin if I don’t feel comfortable. The proton service is outstanding and allows complete control of the masked email use as well as a password manager and a 2FA for each account if desired and their vpn. The combination of these 2 services has been perfect for me. I won’t go back to ironvest if and when they ever get their act together. Too costly versus what I now use.
