UPDATE: The Check for Updates feature has been restored in Version 1.19. To access this updated feature, please select “App Info” from the sidebar.
Version 1.18 temporarily disables the Check for Updates feature introduced in Version 1.10. This is because we are working on a new system to make the Check for Updates feature more easier for us to maintain on our server. So in the meantime, it will be disabled and we will reintroduce the feature, as well as a new and improved help system, in Version 1.20, our next major update.
Thank you and sorry for the inconvenience.
