Schlage Encode (not plus) Virtual Key Issue

Just purchased a Schlage Encode deadbolt. Trying to add my wife as an admin using virtual key feature. My wife is already signed up for Schlage home app under her own email address. After adding her as a virtual key admin in my app, I email the invitation link. When she clicks the link, it opens the Schlage home app but simply gives the options of (paraphrasing) “Owner has to invite you to use existing lock” (I did, that’s how she got the link) or click to add a new lock, which we can’t because the lock was added under my email address during setup. So basically my wife is sitting under virtual keys in my Schlage app “pending” whilst clicking the invitation link does nothing in her Schlage app when she clicks the link. Either this issue is unique to me, or the documentation from Schlage is not great in detailing what the virtual key recipient needs to do, or maybe both things are true? It does mention the virtual key will allow the recipient to lock or unlock the door with Bluetooth when nearby, but that doesn’t seem to happen either. I was wondering if the encodelus was needed for some of this functionality (I have not-plus), or if I am missing something in Schlage’s documentation? Or maybe I’m trying to do something that just isn’t gonna work?
