Updating Bamboo, Colorfield, Oust or Room and Pillar - The September 29 versions (Bamboo 1.3, Colorfield 1.2, Oust 1.7, Room and Pillar 1.25) are signed with new keys, so Android will not install them over an older version. Uninstall the old app first, then install the new one. Only the menu settings are lost.
To install - Download the file on your Android phone and open it. The first time, Android asks for permission to install apps from your browser or file manager. Allow it, then tap Install. Google Play Protect may offer to scan the app first, which is fine.
