Describe the bug

Describe the bug

Variation+Remix using Custom API only works on Vary (Strong) action and hangs on the Vary (Subtle) action.

Expected behavior

Should work on either actions.

Additional Information

When executing the client.init function, discord opens the settings form an I see that the "High Variation Mode" is selected. It might be the reason. If so, how can we overcome this?

error log

None, just hangs.
