When updating or generating a profile for the first time, you will see a loading bar letting you know how long it will take to give you updated information on that person or company. Loading a profile typically takes a few minutes to get the most up-to-date information.
You won't need to wait for the profile to be generated and can let it update/generate in the background and come back later to check on the profile. You can see your last visited profiles in your dashboard or on the recents tab.
