Multiple vault - cannot add a secondary vault with a second OneDrive account

[Arnie]

Samsung S9+ / default browser Edge

My primary vault is synced to OneDrive via my Microsoft account. When I try to add a secondary vault and sync with another OneDrive account it switches to the browser for authentication. It automatically goes to authenticate with fingerprint (via Enpass) but Enpass then apparently tries to sync with my primary account and tells me "No two vaults can be connected to same account for syncing data- connected vault:primary".

I solved it by setting Chrome as the default browser which does let me log in to the second OneDrive account. So apparently this is an issue with Edge?

Tried different settings in Edge with Autofill, but that didnlt help.

I solved it while writing so I thought I might as well leave the message.
