[anthony-nhs]

Which web client version did you detect this bug with?

v1.25.0

What environment (build systems, module system, and framework) did you detect this bug with?

TypeScript v5.0.2, Webpack v4.46.0, ECMAScript modules (ESM) and React v18.2.0

Is your web application a single page application (SPA) or multi page application (MPA)?

SPA

Please provide your web client configuration

{
allowCookies: false,
endpoint: "https://dataplane.rum.us-west-2.amazonaws.com",
guestRoleArn: "arn:aws:iam::000000000000:role/RUM-Monitor-us-west-2-000000000000-00xx-Unauth",
identityPoolId: "us-west-2:00000000-0000-0000-0000-000000000000",
sessionSampleRate: 1,
telemetries: ['errors', 'performance', 'http']
}

Please describe the bug/issue

We initially create the client with config above - note allowCookies is set to false

We have a cookie preference banner and page, that if the user consents to allowing cookies, we call allowCookies(true) against the web client
When this happens, then user journey data is not shown in the aws web console ui in the user journey tab

This fixes it for us - #698 - but not sure if there is a better way of doing this than recreating the objects when config changes
