Concurrent AccessToken Requests Not Working?

[spottedmahn]

When I make multiple concurrent requests for an access token I've receiving timeouts and multiple B2C requests to get an access token; it is not pulling from cache storage.

I'm about 98% confident this was working w/ 0.1.3. There have been some changes to our app but not much w/ regards to these components.

Please see the MSAL.js log below.

See how there are multiple requests to get access tokens within seconds of each other?

@spottedmahn I apologize for the late response. I was busy working on build related stuff.
Can you please try the latest dev branch and see if it resolves the issue.

I just created a test case to send multiple acquireToken requests for different scopes on app start and was able to get access token for all requests using the latest code.

Seems to be good now, thanks 🙏
