Hi Roman Hess,
Thank you for reaching out to us.
We’ve reviewed your query regarding changing the caption of the Ribbon Backstage button. In our testing, the BackStageHeader property correctly sets the caption for the BackStage button as expected.
To assist you further, we’ve attached our testing sample demonstrating this functionality. We kindly request you to test this sample on your end. If the issue persists, please modify the sample to replicate the problem and share it back with us. This will help us investigate the issue more effectively.
We look forward to your response and are happy to assist further.
Regards,
Sekar Sivalingam
