I have my bank account linked to my paypal for sending money. I was able to send 50 euro without issue but a few minutes later when i tried sending 35 euro its saying i need to set up a funding source .... i dont understand as my bank is set up and it worked the first time
As you have not added your country to your profile (so we can see when we hover over your username) or said in your post which country you are in then sadly can't advise. Paypal varies a great deal country to country so you need to tell us where you are on this worldwide community forum.
