Hi, AndréL365!
Welcome to Microsoft's Community.
Based on your inquiry, we understand that you are experiencing issues with the Learn Platform. We will gladly help.
We invite you to provide us with a PSR (Problem Steps Recorder), so we can have a deeper understanding of the situation.
Problem Steps Recorder (PSR) is a software used for capturing information about procedures on a computer. This information includes a picture of the screen during each step of the situation and a text description of the selected areas. We will use this information to take a further step in the resolution of this issue.
Here are the instructions for accessing the PSR tool, depending on your Operating System:
Some considerations:
The file has to be sent as a Private Message in .zip format.
The tool only collects the last 25 screenshots. If you need more steps recorded, refer to the “Adjust settings” section to increase this value.
These instructions work on Windows 7 and later versions.
PSR does not capture any keyboard entry during the recording. If any input is important to re-create the issue, you can use the comment feature.
Please make sure the error is clearly visible in the recording.
Remember to send the record in .zip format through the Private Message we have opened, where we will request information related to your Certification Profile in order to verify it and address the request accordingly. You can access the conversation by clicking on the icon located on the top right corner of this page, it looks like this:

Please note that we are unable to change the defined times for a response at this thread.
