On the Perspective mobile app when using the 'launcher' it will open the same instance if one was launched previously. However, if you create a shortcut of the project, it will always create a new instance. Sometimes this isn't desirable.
Would it be possible to create an option to use the same instance for shortcuts.
As a side note, I often find that if multiple instances of the same project are open on mobile I often get timeout errors on first load. Closing all instances and starting a new one fixes the issue.
