Tips to keep charm pass loaded?

Ok there is one conductor on the Penn line who always looks at me like I kicked his dog when my already activated CharmPass ticket takes forever to load.

You know what I’m talking about, right? You activate your ticket, get on the train, and then 30 minutes later when the conductor comes by to check tickets, the app is just stuck on the opening screen for a couple of minutes.

Any tricks? This dude truly hates me.
