Weird Weather Data Error message, HELP!

[Kencc]

I have a problem I hope you-all may be able to assist me in. About the time the latest Android update (through AT&T) was installed, on a ZTE 958 ZMAX, running Marshmallow 6.0.1, I started receiving a persistent error message on my phone, a gray box, at the bottom of my screen, that says something about weather data exceeding my limits. It is only on my screen for a second, and is gone before I can read it, but it will not go away and comes up every 30 minutes or so. I have determined it is not something I installed as I removed all of my weather apps, except those in the root download, but the error continues to return. When and IF I am able to capture it on digital I will post it here but only believe it has something to do with the latest Android update. Any Ideas? Should I start a new thread on it? Thanks again!
