I have a number of Kasa smart home devices and am OK at troubleshooting. Just got KL60 bulb. I can connect with Iphone but the app won't find the device. I tried factory reset and a bunch of other tricks but no luck. I then used an android tablet and it found the device right away. Now that its linked to my WiFi, everything works with Iphone. Maybe bug with Ios 14.01.
