Troubleshooting Version 15 #99138

https://thebrain.zendesk.com/agent/tickets/99138

Hello Bernd,

Thank you for the detailed message, that helps a lot. I’ll go through this step by step and focus first on the items that affect data safety and version compatibility.

First, just to clarify the version:

There isn’t a TheBrain version labeled “23.12.25”. Could you please confirm the exact build number shown under About? The latest available build at the moment is 15.0.95.

Regarding the sync error about unsafe attachment names:

This usually affects a specific Brain rather than all Brains. Please open the affected Brain in TheBrain 15 and run a data integrity scan:

• Three horizontal bars
• Brain
• Perform Data Integrity Scan

Let the scan complete fully, then try syncing again.

About Brains no longer opening in version 14:

This is most commonly caused by Light Sync being enabled when the Brain was opened in version 15. Version 14 cannot open Brains with Light Sync attachments enabled.

To restore compatibility:

• Open the Brain in TheBrain 15
• Click the Sync icon
• Disable “Light Sync attachments” for that Brain
• Close TheBrain 15 and open the Brain again in version 14

For the language issue:

Please check that your operating system language and TheBrain’s language setting are aligned. In version 15, you can search for “language” in Settings to find the relevant option. If the interface still does not switch to German, please send a couple of screenshots showing the language setting and the UI so we can verify this on our side.

The remaining points you mentioned (gesture zoom, scrolling speed in split view, and the missing “insert new page” option) are related to differences or ongoing work in version 15. Once we’ve confirmed that your Brains are syncing cleanly and opening correctly in both versions, we can go through those behavior differences in more detail.

Please start by confirming the exact version number and let me know the results of the data integrity scan.

Best regards,

John
