@ejsllc sounds like you never linked your subscription. When you purchase through iOS it’s done through the App Store. Instructions are at https://support.brave.com/hc/en-us/articles/13405790544653-How-do-I-add-a-new-device-to-an-existing-VPN-subscription
Been asked and answered a lot. So I’m shocked you didn’t find the solution. For example:
- Can't Sync VPN to computer - #2 by Mattches
- Connecting Brave Firewall + VPN to Brave Account - #2 by Lou-ee
- Can’t turn on VPN on other synced devices - #2 by Saoiray
- Brave VPN Activation on Other device - #3 by Mattches
- Connecting Brave Firewall + VPN to Brave Account - #2 by Lou-ee
- Linking account from mobile to desktop browser - #2 by Saoiray
