Yes I've had awful problems with it .

I've actually lost money.

Problem with a QR code meant I had to pay for postage, felt obliged as buyer had paid for item so lost me money.

Wasted half a day phoning E bay customer services who were unable to help.

Had two problems and it really stressed me out, can't risk it going wrong again and going  through all the stress again so have decided not to use eBay in the future.

A pity it was so easy before.

Cheers.
