What’s new
Subscribing is now reliable. Plans are fetched from Google Play with retries, so a slow connection on first launch no longer leaves Subscribe failing with a "temporarily unavailable" message.
Also in this update:
- Caption words now fade in as they animate, instead of snapping to full opacity and then growing into place.
- Fixed the Scanline style, whose sweeping highlight was invisible.
- New caption lockups, including text placed behind the speaker.
