Unable to add multiple Portals

[joeroganDOTca]

Describe the bug
Trying to add multiple Portal and AGOL environments to ArcGIS Assistant but mostly does not work. Seems that if I add an AGOL org first I can then sometimes add a Portal org after that, but only one. Very inconsitant.

To Reproduce
Steps to reproduce the behavior:

1. Created app items in each environment and registered the redirect URI with each and saved the App ID for each to use with the sign in. We have 6 Portal environments total, half of them requiring VPN, the other half are public internet. All of these I’m using Admin user types.
2. Signed into the ArcGIS Assistant with my Dev Portal user, I see it added to the account list in the top-right menu.
3. Tried to add any other Portal with the “Add Enterprise Account” button. This does nothing and was still on my Dev account. Tried it several times with various Portals, but none appear in the list, always stuck with the Dev one.
4. Added an ArcGIS Online account, this was successful. At this point I have two available accounts in the list, one Portal and one AGOL.
5. Tried again to add a Portal account, this time it worked and now have 3 accounts listed.
6. Tried to add another Portal account, but same problem that it doesn’t show up or change accounts.
7. Added another AGOL account successfully.
8. Lost track of my steps here when I did them, but managed to get a 3rd Portal account added, after more than a dozen attempts.

Expected behavior
Expecting to add a Portal and get a Portal in the list.

Screenshots

Desktop (please complete the following information):
Windows, Chrome version 98

Additional context
The Chrome console gives warnings about CORS, but adding the ArcGIS Assistant URL to the Allow origins list in the Portal setting doesn't change anything. Also, if you can see the above screenshot, it is very difficult to know which organisation is which when they all start with the same long text. Need to hover over this to see the full organisation name.

Unable to test the new ArcGIS Assistant with migrating new storymap templates between environments until this is fixed. Have worked with Esri Canada on a ticket for this issue, and this app was their solution. They will not support this app or bug and told me to post this issue here.
