Switching Back to Version 14 #99624
https://thebrain.zendesk.com/agent/tickets/99624
Hello Russ,
Thank you for reaching out and good question.
Before opening your Brain in version 14, please make sure Light Sync is disabled in v15 (for each brain). Version 14 does not support Light Sync, so attachments need to be fully downloaded for backward compatibility.
In v15:
Open your Brain
Click the sync indicator near the top
Disable Light Sync for attachments

Allow it to fully download attachments before switching
You do not need to uninstall version 15. Versions 14 and 15 can both be installed on the same machine. You just cannot run them at the same time.
Once Light Sync is disabled and attachments are fully downloaded, you can open the same Brain in v14.
Best regards,
John
