There's a bug on Cloudflare's side that prevents existing accounts from getting Warp+ even after you bind a correct license key. If you have ever connected to Warp VPN, then your account is affected. Essentially, you need a new account that has never connected to Warp VPN for "warp=plus" to show. Otherwise, you'll be stuck with "warp=on". Whether that is just cosmetic or really the case, nobody knows.

According to @galpt in #84 and this Reddit discussion, some people are having problems with WARP+ after changing their key. If you are one of these people, please post here so I can track the significance of this issue. I will try to investigate in the next few days, but until then, @galpt has posted a workaround:

How to fix the WARP+ issue

Based on this post, some people are unable to get the warp=plus working and only get the warp=on even after they've changed the license key. However, you can solve this issue with some simple steps:

⚠️ Please save the WARP+ key on your phone before doing any of these steps.

1. After generating the wgcf-account.toml, use the license_key from the file on your phone
2. Open the 1.1.1.1 app
3. Click on the hamburger menu button on the top-right corner
4. Navigate to Account > Manage devices and you'll see your wgcf device there
5. Now, copy your WARP+ key back to Account > Key and to the wgcf-account.toml
6. After that, run this command

wgcf update

1. After running the command, connect using WireGuard
2. While connected, run this command to see if it works as expected

wgcf trace

1. The result will show warp=plus instead of warp=on

[Note] If it doesn't work, you probably have to repeat step 1-5 since the fix is between these steps.
