Warning when switching between providing Hotspot and using Wi-Fi & visa-versa

[Android Central Question]

When switching between using WiFi and providing Hotspot service to other devices on my Motorola Droid Turbo 2, I get a warning that my Wi-Fi connection will be turned off and I have to click on OK to continue or Cancel to continue using Wi-Fi. I want it to continue to prompt me. It used to prompt me with a similar warning going the other way, that is, from providing Hotspot service to using Wi-Fi but I must have checked the "Do not show this again" option. How and where can I turn this warning back on? Also, if I accidentally turn off the warning for going from Wi-Fi to Hotspot, where do I turn this warning back on?
