My powerschool is working fine , except when I press powerschool pro to get the assignments of my students or add more assignment, the pages keeps on loading forever, even though all the other features are working fine and the internet is not slow.
A known reason that would cause the assignment screen to be stuck on loading would be if there is over-accumulated cached data or cookies on your browser.
Please try clearing the cache and cookies on your browser. Make sure to select the "All time" option from the drop-down, as shown in the example below.
An alternative would be to use a different browser. If you are using Google Chrome or Safari, try using Mozilla Firefox or vice-versa.
Please let us know if that helped you find a solution.
