Implementation of an RTC on nrf52832 - drift issues

Question

Hi-- 
 I tried to implement an internally managed RTC using the app timer library, but came to find the error on that is too much for an RTC (~25 min lost over a few days). I started trying to find other alternatives, and came across this github repo: https://github.com/NordicPlayground/nrf5-calendar-example 
 The issue I am running into is it seems to be conflicting with my fStorage implementation in the code. Without the code built into my project, the fStorage functions fine as is. When the calendar code is brought in, the fStorage implementation keeps failing (with a no memory available error code designation). Is this expected? Does the calendar implementation conflict with the use of a soft device? Is there any way around it if it does?

Misery breeds company! Yeah, the actual issue was I switched everything over to RTC2, but I masked the register compare wrong (RTC2 was already enabled in the config header file). Once I fixed that error, I was good to go

 In the README of that example it is stated that this example does not support the softdevice. You can also see that it uses RTC0, which is used by the SoftDevice, so using these together will create issues for sure. RTC1 (if not using app_timer) and RTC2 should be free to use though.
