Version 1.2
Your access now comes from one of two places only: the free 14-day trial you start yourself, or the one-time Full Unlock. Both are restorable with the Apple Account that owns them.
Also in this update: photos on the timeline no longer re-encode on every edit, so editing and export are faster; playback and scrubbing are smoother; and a fix for a case where a running trial or a completed purchase could briefly be reported as missing and an export refused.
