So, you took the version of Pure Maps from SFOS 4.6 and made an update to SFOS 5.xxx. That’s the same problem.
In general, don’t be surprised if apps compiled in Chum for SFOS version that is different from the one on the device start crashing. And don’t start submitting it as a bug to the app as you will be wasting time of the developers to try to figure it out and ask you about it. Dependencies can change between SFOS versions and we may have to recompile it for new SFOS version. That’s what Chum is doing and please wait till Chum starts supporting your SFOS version before issuing bugs at app repositories.
