Update required

Every version of KUVRT works for 90 days after it comes out, and KUVRT stops serving versions that are too old. An out-of-date KUVRT shows "Update required". It keeps your chats readable and lets you export them, but it sends and receives nothing until it is updated.

1. Open KUVRT while you are connected.
2. Tap "Update now". If it says "Check for an update" instead, tap that, and then "Update now".

Messages sent to you meanwhile wait for you and arrive after the update. If KUVRT stays out of date for a long time, the people who wrote to you see "Not delivered - it waited too long and was never picked up", and can send it again.
