I can register on my cell phone with my school account. If I download the app on the laptop (windows 10) and want to log in or log in to the browser, the tab either loads forever or the following occurs:
"We were unable to log you in. Please contact your system administrator." And an error message.
why does it only work on my cell phone and other devices? As I said, my laptop is even newer than my cell phone
Then ask the person in charge at school. However, I suspect that you can only log in on one device.
I would ask the school secretary instead, or simply your computer scientist. Now it is a bit difficult due to the virus but email them.
No, actually it is not. I was able to register anywhere
That was a guess. It is certainly also possible to add a restriction.
There are apps that only work properly on smartphones and tablets running Android or iOS. (We had a video chat program today.)
It may also be that your browser blocks scripts or something similar. Have you tried another browser before?
Apparently it's not the browser: /
and a week ago I was even able to use the laptop, but since then no longer stupid
Are all unfortunately not available
No, a week ago it was unfortunately not possible since then
This is an interesting piece of information.
Have you ever had a Windows update?
