iOS sometimes loses angular variables when resuming from the background

I would imagine I will need to do quite a bit of reworking because I would need to wait for the local storage promise to return the value (using “then”) and I would not be able to use the current method where I am just referencing the variable directly

I would look at this as an opportunity, because the design you have now does not provide any way for GlobalProvider to signal changes in any of these variables. Incidentally, you should not be manually instantiating Promises as setCustomerId is currently doing: see this article for why. Also see this post for example code involving this general idiom.
