I’m sorry for the frustrating experience using Language Forge. While I would like it to work for your project out-of-the-box, the reality is that the Send/Receive with FLEx is very much an in-progress feature. When we get reports of projects that don’t sync as expected, we create issues for them so that an available developer can work on fixing that part of the sync. This is unfortunately a very slow process this summer due to vacation and other factors. We are a very small team with a big vision and often aren’t able to respond to everyone’s request for help. I will reply to your email with an issue regarding syncing.
