Ghost Icon - My Telus on phone

There are a number of things to discuss here. First up, when was the last time you power cycled your phone? Almost always people have tried that first, but it's always worth asking. Another option would be resetting Settings (you'd need to reconfigure your Wi-Fi / Bluetooth connections after of course) as that can help as well. Yet another thing to note is that sometimes people suspect it's the app itself but it's actually a website shortcut.

Screenshots would help, would you be able to share any so we can check in with our Mobility team?
