I believe that has to do with the new security protocols put in place by iOS. You will also see an option for Local Network, when this is off, it will not scan your network and you may have issues. I was just in another thread where someone turned it off and there issue of the prompt shown here, I believe, went away.
So you can try going into the iOS Settings App, scrolling to the bottom and select the Wyze App. Then turn off Local Network if it is on and see if this message goes away.
Here is a description
Local network privacy provides added transparency when apps connect to devices on a person’s home network . If your app interacts with devices using Bonjour or other local networking protocols, you must add support for local network privacy permissions in iOS 14.
