While building my app ThinkBack I decided to use Realm as my underlying data-store. ThinkBack helps users commit notes or ideas to long term memory through passive, daily recall. To support changes and new features in the app I need to modify the existing Realm JS object model that defines the schema. Modify Schema and …
While building my app ThinkBack I decided to use Realm as my underlying data-store. ThinkBack allows users capture notes and categorize them using hashtags.

We switched a number of users from one active directory domain to an entirely different one, which K2’s cache wasn’t aware of. This caused some users to be missed when resolving the workflow destination active directory group …
