Description

Hi,

We are using Azure B2C for our angular web app authentication and we have noticed multiple token calls being made after acquiring token with in fraction of seconds, even before the obtain token has expired. Eventually failing with ERR_HTTP2_PROTOCOL_ERROR message intermittently , causing page to refresh and losing all the user activity on the page when this happens.
we suspect something is clearing the local storage cache for the token , which is initiating the acquire token call again. only time we are clearing out the local storage cache is on sign out in our code.

PS: I'm unable to upload a screen shot of the network logs. but mentioned the verbose logs and stack trace

Error Message

Request: https:////b2c_1a_userworkflow/oauth2/v2.0/token
Reponse: ERR_HTTP2_PROTOCOL_ERROR

Reproduction Steps

use msal angular library for token acquire and management.

Expected Behavior

expect only 1 token call and use the same token to make subsequent api calls until token is expired.
