This build addresses bug fixes and has usability improvements:
The entire Katch app infrastructure was revamped to improve performance, stability, and latency.
You are now notified when your contact is available to connect via a Katch call. A push notification is sent when one of your contacts who you have sent a Katch card, or prioritized one from them becomes available.
We made UX improvements including labels on the various batches when you go to prioritize and send Katch cards.
We revamped the entire push notification infrastructure to enable Katch users to get notified at appropriate moments for Katch calls and cards.
