We love our Kasa smart plugs and switches, so much so that we now have 30 or 40 of them in our home.  However, we are very upset that the iPhone app with its most recent update has become almost unusable due to periods of "freezing" or hanging up for ~15-30 seconds every time you start the app or switch to it from another app, and then more freezing for shorter periods of ~5-10 seconds intermittently after that while simply using the app.  

This is incredibly frustrating!

Some facts:

* We have a mix of HS100, HS103, and HS105 smart plugs and HS200 smart switches 

* All switches and our phones are connected to the same wifi network

* We have the same problems on all of our family iPhones, including a brand new iPhone 14 just added, and iPhone 12, iphone 11, and iPhone X

* All device firmware is up to date as far as I know 

* Our App version is the most recent

Please help me understand how this problem can be fixed!  Otherwise we will be forced to abandon the entire Kasa ecosystem.

Thank you.
