Jason, I’m wondering if it might be helpful to split up this wishlist item by product?
Its current organization makes it feel to me (and maybe users and dev team) somewhat insurmountable but there is a lot of opportunity between where we are right now and a full app rewrite.
Perhaps by combining all sharing issues into a mega-thread it’s possible smaller but more feasible incremental changes are missed?
Yes, ideal pie-in-the-sky option is multi-user multiple-permission-type selection but if that takes a whole app rewrite that isn’t in the cards for the next 2 to 5 years then maybe there’s room to optimize the current sharing defaults within the app? How best would that data be collected?
For example, for Wyze Cameras, if previously the app did support SD card viewing then I think there would be near-universal approval of a ‘warning modal’ when enabling user sharing. Similarly, I can’t imagine most users want to give shared users permission to disable cameras.
Likewise, for the Wyze doorbells, it’s very difficult for me to imagine a scenario where you’d want to share a doorbell but not share notifications (even if you can’t setup the video tunnel to subordinate devices/accounts to allow answering).
Perhaps, the dev team has ideas on how best to solicit feedback given the constraints on app architecture rewrite, maybe “multiple users’ permissions for shared users across the entire Wyze product line” thread can replaced by something that narrows down the requests and highlights what’s possible now?
I may be totally wrong, though so no hurt feelings if there’s a better way of getting actionable shared-user requests that match the ethos of Wyze, the capability of the current architecture and are highly requested by users.
Engaging the dev or engineering team on how they’d like to measure that may not be easy but hopefully Wyze encourages that 
Good luck on the go-betweening
