Native v6.2.2

This release introduces a theme-appropriate splash screen on app launch, ban/unban controls for public groups, and offline queuing for message edits. We've boosted SQLite database speed and made @ and ~ mentions more responsive. This version also addresses several bugs including navigation loops, emoji reaction display issues, image viewer problems, contact editing glitches, invitation failures, login hangs, and notification crashes.

• Adds a light/dark-mode-appropriate splash screen when launching the app
• Adds banning and unbanning functionality for public groups
• Adds offline post queuing for message edits
• Improves ~ and @ mention responsiveness in Chat channels, DMs, and comments
• Improves SQLite performance
• Fixes an issue where tapping "Customize" in an empty group, then tapping "Cancel" would result in an inescapable navigation loop
• Fixes an issue where users needed to leave the DM and then return to see emoji reactions in threads
• Fixes an issue where swiping down to exit the image viewer lightbox would preemptively trigger while the image was zoomed in
• Fixes an issue where editing a contact's nickname, then editing another profile would show the previous contact's details
• Fixes an issue where pressing "Invite people" from group context menus would fail to navigate
• Fixes an issue where logging out, then logging back in would hang the app on "Loading…"
• Fixes an issue where rendering notifications from some Gallery channels would crash the app
