How to Check if Changes to Wireframes are Saved in Relume

Hey guys, is there a way to see if my changes to the Wireframes are saved in Relume? More detailed: I was working on the Wireframes in Relume, making changes to the copy, changing components, everything was soon ready to be exported to Figma. Then suddenly I could not edit anything anymore, so I reloaded the page and all changes I made in the last hmmm 90minutes or so were gone. As if there was a rollback on the server/cloud. Hope you can help 🙂
