[Bug]: Content Cards of old user are shown to new user

[psimk]

Braze Web SDK Version

4.4.0

Integration Method

NPM

Browser

Chrome

Steps To Reproduce

Setup

I created a small React application using

npx create-react-app

Installed the Braze SDK

npm install @braze/web-sdk@4

And updated the App.js file to include:

import { changeUser, initialize, removeAllSubscriptions, requestPushPermission, subscribeToContentCardsUpdates } from '@braze/web-sdk'

function App() {
  return (
    <div className="App">
      <button onClick={async () => {
        try {
        removeAllSubscriptions()
        } catch {}

        initialize(
         '<insert-api-key>',
          {
            enableLogging: true,
            baseUrl: 'sdk.fra-01.braze.eu',
            enableSdkAuthentication: false,
          })

        requestPushPermission()
        subscribeToContentCardsUpdates(console.log)

        changeUser('repro-user-1')

      }}>use User 1</button>
      <button onClick={async () => {
        try {
        removeAllSubscriptions()
        } catch {}

        initialize(
         '<insert-api-key>',
          {
            enableLogging: true,
            baseUrl: 'sdk.fra-01.braze.eu',
            enableSdkAuthentication: false,
          })

        requestPushPermission()
        subscribeToContentCardsUpdates(console.log)

        changeUser('repro-user-2')
      }}>use User 2</button>
    </div>
  )
}

Actual Reproduction Steps

1. Launch Reproduction Application
2. Click "use User 1"
3. Send out a test campaign for user repro-user-1
4. Click the Notification for the test campaign (this should open the application)
5. Click "use User 1"
6. See the console log containing the test Content Card
7. Click "use User 2"
8. See the console log containing the test Content Card

Expected Behavior

I expected that the content card would be tied to the user I sent the content card for "repro-user-1". "repro-user-2" should not have received the content card.

Actual Incorrect Behavior

"repro-user-2" receives the same content card as "repro-user-1", even though it was sent only for "repro-user-1".

Hi @psimk. I followed your steps and was unable to reproduce. If you look at the third instance where it prints out content cards, you can see that it is actually erasing the content cards as you change user. I recommend that you send an email to support@braze.com with this information along with links to any relevant campaigns. I'd also recommend that you print out the cards contained within the content cards object so our support team can see which cards are being sent to both users.
