I've been unable to use the data plan on my Nexus 4 on a Straight Talk plan after updating to Lollipop.
Data's not working, and I keep getting a notification that says "Sign into network HOME". When I tap on that notification it takes me to a blank screen saying "Sign-in to network". The only options I have is in the drop down menu in the top right:
- Do not use this network
- Use this network as is
When I choose the latter, my data turns on for a second and then stops working again almost immediately.
