Hello everyone! So a favorite tap of mine (GoodNotes) has just added a collaboration feature. This is similar to iWork and other apps where you can invite users to work on the same project as you. My question is this: Does GoodNotes have to pay for server space on AWS / Azure to make this collaboration happen, or does all this iCloud use as a pipeline with the files stored on each user’s device and automatic updating while working on the projects ?? I ask because I work with an app and am unsure of how this type of feature works technically. Thank you in advance for your wisdom.
