As a best practice, multiple versions of the Mobile Healthcare app should not be installed and used on the same device concurrently. When the OnBase app is integrated with Epic, the functionality of the OnBase app is driven by integration links configured in Epic. When using iOS devices, if multiple versions of the app are installed on an iOS device and a user taps a button in Epic configured to open OnBase, the OnBase app cannot determine which version of the app should be opened.
