Synchronization is sending your project from the application to the platform. However, you must be vigilant during this step. Indeed, some bad handling can cause a bad synchronization which will cause the disappearance of some/all your rushes but also it would be impossible for you to read them.
To avoid this kind of concern, we recommend:
- Submit your project using only the application or platform
- Avoid going on the project on the platform during synchronization.
- Avoid any action on the project during synchronization.
- Check that the network is stable
