Which is a massive pain to use for stuff like this, and it explicitly recommends against using it with apps that use notifications when you enable it. It shuts down constantly, like as soon as your phone locks (at least for me), and won't process push notifications until the space is opened again.
I really don't get why they don't just give you a thing to install something as many times as you want. It's insane that you still have to use these weird workarounds.
Given all the commentary it's very clear you don't understand and have taken zero time to enlighten yourself on Private Spaces.
You do realize you can still create a work profile through things like Insular/Island, right?
It's insane people complain about these things when they're legitimately non-issues
You can configure the private space to lock when: - Every time device locks (default) - 5 minutes after screen timeout - Only after device restarts
The last option would work just fine for you
