@gviedma-aulasneo, if you can provide more information on how to test it or what the expected behavior is, that would be great.

Steps to reproduce the test:

• Log in to the platform with a user that has the Global Admin or Library Admin role.
• Open the Admin Console for a library where that role is applicable.
• Open the Add new team member modal using the Add new team member button at the top right of the screen.
• Block the request to ulmo.demo.edly.io/api/authz/v1/roles/users/ (see tutorial: https://developer.chrome.com/docs/devtools/network-request-blocking).
• Fill in the modal fields and click Save.

Current behavior:

• A retry toast appears in the lower right corner of the screen.
• The toast disappears after a few seconds.
• Another toast appears.
• Eventually, that toast also disappears.

Expected behavior:

• The toast remains visible until the user either retries the action or explicitly closes it.
