I’m trying to add items to my watch list and I keep getting 

add error: There was an error adding the item, try again.

is anyone else having this error come up for them and is there anyway to fix it. 
I’m using my iPhone when looking and buying on EBay.  Thanks in advance.

Try adding to your watch list on a computer using the full site.

If it works you will know it's an issue with the app.

It’s definitely an issue with the app as I’ve tried it on 2 different phones and I still get the same error, can’t try it on a computer as I don’t have one.
