Before we go any further, could you please provide me with more information regarding the issue you're having with extracting/running reports? If there is an error message, please provide it to us. You can also include some screenshots of the error.
In the meantime, I recommend we perform some basic troubleshooting steps to check if you're experiencing browser-related issues.
You may reload your browser by pressing F5 on your keyboard or selecting the Reload symbol. After that, log in to your account in a private browser and follow the instructions below to fix this unexpected behavior. The following are the shortcut keys:
Google Chrome: Ctrl + Shift + N
Mozilla Firefox: Ctrl + Shift + P
Microsoft Edge: Ctrl + Shift + P
Safari: Command + Shift + N
If you're able to get the reports with ease, then you'll have to clear your browser cache regularly. It repairs any problems with your browser and refreshes the settings. You can also use other browsers that are compatible.
