When using Amplitude and AppInsights together on the client side, the browser is flooded with error messages like below.
Access to XMLHttpRequest at 'https://api.appcues.net/v1/accounts/111111111111111' from origin 'http://222222222222' has been blocked by CORS policy: Request header field request-id is not allowed by Access-Control-Allow-Headers in preflight response.
Is is possible to make appcues accept the “request-id” header for OPTIONS request?
