Prevent other accounts message notification header to be displayed when a message is received on the default account

Fixed 'you have joined the group' chat event for created group icon not matching others + added new icon for admin rights granted event

Forgot to change the label of sign out button in the confirmation dialog + hide delete account message for third party accounts

Added back round corners to main lists in portrait mode (keep round top bar in landscape) + increased space at the bottom of the avatar in top main bar

Fixed issue with top margin, specifically visible when in landscape + reduced spaced in drawer layout for phones in landscape

Wait for adapter to contain data before attaching it to recyclerview to prevent loosing scroll position when rotating device
