[German]There was a disruption of Microsoft 365 services (I got first reports on April 19, 2023) during the last hours. User can't reach apps in Microsoft 365 – the page ist empty. Microsoft investigated that and has now recovered, according to tweets dated April 20, 2023. Here is a short overview, what we know so far.

There have be access problems with Microsoft 365 services reported, that has been confirmed by Microsoft, as can be seen from the following tweet from Microsoft 365 Status. Microsoft states that more information would be available in the Admin Center under OO544150 (later they changed it to MO544165).
The Service Health Status page didn't indicated the disruption at the time I wrote the German blog post. Also other sites like downdetector didn't report to many incidents – it seems that it was a scattered issue. On reddit.com someone in this thread reports, that apps are missing, but he can manually access old links and go to Admin Center, Onedrive, etc. But the portal.office.com page does not work.
Bleeping Computer colleagues here pulled the status text "Users may be intermittently unable to view or access web apps in Microsoft 365. We're reviewing service monitoring telemetry to isolate the root cause and develop a remediation plan." from the Admin Center. It also says that in some cases, users would be greeted as "new" and prompted in a banner to contact their administrator for help with the issue.
"New to Microsoft 365? This is your Microsoft 365 home page, where you can see and access all your applications. If it's blank, it could be that your user license was only recently assigned to you."
However, I had already posted the above message on April 19, 2023 in the German blog post OWA-Störung? Telefonische Produkt-Aktivierung; iOS-Geräte machen Probleme mit Exchange 2013. German blog reader Christian had reported that web apps were currently on strike for him. To this he wrote via e-mail:

We currently have the problem that the web applications do not work properly. After logging in, the following message is displayed by Microsoft. Is this problem also known by others?
He has posted the following screenshot, shown, if users tries to access web apps.
On German sit administrator.de I've seen also an entry with many users confirming issues. It seems now that Microsoft has fixed the flaw.
