Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I'm having a similar problem when trying to use Excel files in Personal OneDrive as data sources in Power BI. Two days ago, I successfully used 'Embed' -> 'Generate' in online OneDrive to get the resid and authkey I needed when getting data from the web. I used it in Power BI and it worked. Today it stopped working, so I went back into OneDrive to get another because I assumed it's either dynamic or had expired (another problem, but let's leave that one alone for now). This time there was no 'Generate' button and whilst the URL I'd used before, which I'd got by clicking the 'Information about this workbook' button after generating, had the same resid as before, there was no authkey. The URL included content like &migratedtospo=true&redeem=XXXXXX, which I'm fairly certain wasn't there two days ago.
