I have 3.1.7. There are two major problems that are very frustrating
When I try to add images to the service that have been previously added, it tells me 'Open LP hit a problem and couldn't recover'. I then need to re-add the image, and then I have duplicate images, both of which now work. This is very frustrating as I use the same images every service.
After saving a service, closing and reopening OpenLP it tells me the service file is corrupt or not the right kind of file. It then loadfs the service but only part of it.
