1) Before reinstalling Keychat, export your data as shown in the screenshot. This file contains all of your Keychat data. After installing the new version, go to the login screen, choose Recover ID, and import the data you backed up. The same data file works across all Keychat platforms — mobile (iOS and Android) and desktop (macOS, Linux, Windows). 2) Right now, Keychat groups can have only one admin, but we’re working on adding the ability to have multiple admins.
