We've pushed out an update for ironSource/Supersonic syncs and we're beginning to sync all available accounts once again. We'll monitor syncs throughout the day before resolving fully.

After a quick investigation we found that ironSource updated their API, currently causing syncs to fail. The integration team is working to add support for the newest changes. We'll have syncs back up and running as soon as possible.
