All day Ive tried to submit a dispute on both the App and PC and the webform just keeps coming up with errors.
One error said it was a known issue and they were working on it. But that was 5hrs ago. Whats going on?

I think they gave you the answer ''One error said it was a known issue and they were working on it.''  IT issues can sometimes be complex to solve.  

Are you within specified time limits?

What sort of dispute would be handy information.

For example an item not received dispute cannot be opened before the last estimated delivery date.

What type of "dispute?

Are you the buyer or the seller?
