User Management Bugs

At any change of the existing user, the settings on the user’s page are not applied. The green application button simply freezes, if you go to another section and return, you can see that the changes did not apply.
1) it is impossible for the user to change the name
2) it is impossible for the user to change the email
3) it is not possible for the user to change the password
4) it is not possible for the user to change the language
5) it is not possible to add a user to a new company (IMPORTANT)

You have to completely delete the user and create a new one. Settings for the user are applied ONLY when the user is created.
And these problems are not when using your own server. But there the administrator has admin rights, and in the cloud manager’s rights.
It really turns out that it is impossible to use the cloud.
Please fix.
