This page details some simple troubleshooting tips for the most common problems that might arise while using Unity Collaborate. You can also visit the Collaborate section of the Unity forum for further assistance.
If you notice that the loading cog has been spinning for a long time, or if the upload stops at 99%, Collab might be stuck. First, check that you’re connected to the internet. If your internet connection has failed, Collab is unable to update. If your internet connection is active, please restart Unity and try again.
If your local project state is the state you want, and your Cloud project state is giving you too many conflicts or problems, open the Services tab and navigate to Settings. From here, click Unlink project, then re-link the project with a new ID to submit a clean new version of your project. To do this, click Select organization in the Services panel and follow the steps to assign or create an ID.
If your Cloud project state is the state you want, and your local project state is giving you too many conflicts or problems, there are two ways to revert to the Cloud version:
Open the Collab History window (Window > Collab History), navigate to the latest revision, and click Restore
From the Unity Launch Screen, click Open and then In the Cloud to open the last version saved to the Cloud.
If both your local project state and your Cloud project state are having problems, but you have an older version you want to go back to Open Collab History and click Go back to…, then unlink the project and re-link it with a new ID (as show in the image above) to submit a clean new version of your project.
