As mentioned in the title, I have a set of 4 plugs and they all respond to Alexa commands around a minute late, especially when not used for a while. If I were to repeat the commands in a row it seems fine, but if I were to command (voice and/or app) an hour later it would respond slow (if at all.) 

This is odd because I have previously purchased a single P100 plug before and it was flawless — still is. They're all connected to the same network and according to the Tapo App all updated to the latest firmware. So what could the issue be?
