Office-js: Settings.SaveAsync() not persistent when used in PowerPoint Online

[ndeeH]

We failed at store validation because the Settings API is not working as expected in PowerPoint Online.

• Create a new presentation with PowerPoint Online
• Add an Add In with use of Settings API to save a value

Example:

var mySetting = new Date().toString();
Office.context.document.settings.set("MySetting", mySetting);
Office.context.document.settings.saveAsync(function (asyncResult) {
    console.log('### Settings saved with status: ', asyncResult.status, asyncResult.error);
});
console.log("### Saved MySetting: " + mySetting);

• asyncResult.status says "succeeded"
• Save the document (done other changes in the slide to force auto-saving)
• Close document
• Trying to get the value when loading the document again:

Office.initialize = function (reason) {
    $(document).ready(function () {
        try {
            var mySetting = Office.context.document.settings.get("MySetting");
            console.log("### Loaded MySetting: " + mySetting);
...

Console-Output:
### Loaded MySetting: null

The setting has NOT been saved with the document!

_The Setting API seems to have a bug in this context (PowerPoint Online?)_

Please validate this issue and tell me if it is a bug. We have to know this for our store validation!
(You could have our manifest to try it out)

quick question is this a content add-in or a task pane Add-in. I am able to repro on content add-ins.

[ndeeH]

Yes! It is a content add in. Thanks for reproducing!
Could you please tell me the internal VSO bug nr for the tester. TIA.

this issue is now fixed !

We see great Improvements in PowerPoint Online - seems that actual many things concerning presentation mode and display of content add ins is revised. 👍
We tested this issue and can confirm that it is fixed.
