Why is waze acting up?

I just took a trip up to Seattle, WA & that last few times I had signal the whole way, this time & with in the last 1 1/2 months I haven’t had good connection with waze. Is anyone else having this issue?

Also, why is the signal showing that I’m about 85 miles from where I really am at times? Just curious.

Are other GPS apps on your phone reporting your correct location at the same time Waze is way off?
