Yes, Radio, I understand that. If I installed every application that somebody somewhere wanted me to install, my phone would have no memory left and it wouldn't update properly.
All of my recent Alexa device acquisitions automatically attach to my network, logged into my account, and worked as intended without the Alexa app. The last time I needed it, I got a stereo pair of Dots working with an Echo Sub. But after doing something like that, I remove the app again so it's not taking up valuabl space, draining resources from my phone, and in general being a privacy and/or security threat.
So, I guess I'll have to install the Alexa app again, opt out of Sidewalk, and then deinstall it again.
