I have disabled text alerts on my account as per Verizon's instructions in this post, have my email set up properly, and still receive their notifications as texts on my Pixel 2XL smartphone. These instructions are not correct. There is also no way to turn them off from the phone either.
We want to do all we can to leave you in control of the alerts you receive on your device, mushrmary. We are sorry to hear the instructions do not resolve your concern. Please share more details about what is happening. What notifications are coming to your phone as texts? What notifications do you wish to turn off? The more detail you can provide, the better we can help.
