Which device or browser are you using?

If the app switch to a laptop / PC with Chrome and trey from there.

It's also worth knowing that,  Friday is eBay's maintenance day , when those indoors at eBay HQ Towers  CaliforNIA,  are tweaking and installing new systems. 

It's still very early hours in the morning there,  so less disruption for their US customers,  but sending things a little awry here in the UK,  especially first thing in the morning.

Try again a little later on,  or as said,  switch devices to a laptop / PC  try Chrome ,  see if it's any better there.
