Unable to simultaneously work in the same PowerPoint file in SharePoint Online

We have a PowerPoint *.pptx stored on a SharePoint where we recently had to add a macro. But after saving it as *.pptm it is no longer possible for multiple people to work on it at once. If one has it opened, everyone else is getting a message to open it with write protection because it's opened already.

What can we do to solve this issue?

    Dear Guido Tauer,

    Greetings! Thank you for posting in Microsoft Community. We are happy to help you.

    As per your description, after you save a PowerPoint file as .pptm format, it no longer possible for multiple people to work on it at once, it seems like people cannot co-author in the PowerPoint file.

    May I know if my understanding of the scenario is consistent with yours?

    If yes, when we tested from our side, we reproduced similar situation as your described.

    According to the information in this Microsoft official article Document collaboration and co-authoring - Microsoft Support****Co-authoring is only supported on modern file formats .pptx (PowerPoint).

    Given this, we're afraid it's not available to co-author in PowerPoint file which is .pptm format. We do understand the inconvenience caused and apologize for it.

    Personally, I could understand your concern, and I completely agree that it would be definitely ideal if we could co-author with other people in a .pptm PowerPoint file. Thank you for bringing thing to our attention.
