I've got a ticket raised and all I get back is they are dealing with it.
This is what I got yesterday.
I see that product team is still investigating on the issue, please allow us some time and I will get back to you with an update.
I'm having the same problem with 1 of our customers.. others work fine!
I hope this gets resolved soon.
I'm from the Netherlands:
- Tried other browser, did not work.
- Tried incognito browser, did not work.
- Checked if I was licensed, I am.
- Checked with other customers, PowerApps is working fine with them.
I'm getting this error when opening https://create.powerapps.com or when I want to edit a Sharepoint list (Customize with Powerapps...)
Could you try running PowerApps on a different network/computer to see if that makes a difference? For example, if you normally use a work computer, try running it at home to see if works. There are sometimes networking/anti-virus issues that can stop PowerApps from working, so this would help eliminate that as a cause.
For example, antivirus that carries out SSL interception like Comodo can interfere with the authentication process. Proxy servers/firewalls can also have the same effect.
This type of network interference usually results in the login-loop problem that's reported here. Also, making sure that the time on your computer is correct is important for the SSL/TLS handshake to work correctly.
The other thing I'd recommend is to run PowerApps in Chrome and to open the 'developer tools' window. If you keep an eye on the console, you might see warnings or errors that could help diagnose the problem further.
Same problem in the UK, tried all suggested actions but none worked. Have got 3 lots of this warning:
A cookie associated with a cross-site resource at http://login.microsoftonline.com/ was set without the `SameSite` attribute. A future release of Chrome will only deliver cookies with cross-site requests if they are set with `SameSite=None` and `Secure`. You can review cookies in developer tools under Application>Storage>Cookies and see more details at https://www.chromestatus.com/feature/5088147346030592 and https://www.chromestatus.com/feature/5633521622188032.
but not sure what to do about it?
