Parting may be such sweet sorrow, but with our Collect app on Android, it is now possible to leave a board you have been collaborating on.
Leaving a board is simple: all you have to do is click on the board, and then click the three vertical dots next to "Share". As soon as you do this, a dropdown menu should pop up. Then, just click the "Leave board" option. This will remove you from collaborating on the board:
Important to remember, is that leaving a board will not delete any content from the board - so your friends will still happily have their files (though I am sure they will miss you).
Please note: this feature is currently only on Android, but we hope to have an update soon for our iOS friends.
