🍎iOS Using older versions of mobile apps?

[1974Mustang]

I have some mobile apps I want to roll back the updates on. The main one is the Wyze mobile app because their more recent updates have taken features away and locked them behind as a paid feature. That's not cool.

But see I'd need to downgrade the software on the cameras themselves, but I want to start with getting an older version of the Wyze app first.

Anyone know where I can source the older versions of these apps for iOS?
