Hi Lukas,
Thanks for posting in the community.
According to your description, my understanding is you have two issues. One is when you open the presentation linked with Excel graphs and click the Update Links button, these graphs won’t be updated. Another is the option “Automatic Update” will be unticked when you reopen the presentation.
For the first issue, as you mentioned, you can click File> Info > Edit links to Files, click “Update Now”. Also, you can click “Open Source”. It will automatically open the Excel workbook and update these graphs.
For the second issue, I would like to collect some information.
- Please make sure you have saved the presentation after ticking the “Automatic Update” option.
- Does the issue exist in a specific presentation? Please create a new presentation and link the same graphs to test. If the issue still exists, please create a new presentation and link graphs from a newly created workbook to test.
- Your Office version
Click File> Account, take a screenshot including Subscription Product and About PowerPoint.
If you have any updates, please feel free and come back to share with us.
Regards,
George
