Very bad day for FR24, 1st showing final reg and now F-WZFX (instead of Y). The Airbus guys even help you with the call sign, you just have to copy it.
I think FR24 have been having a busy day ! They have been rolling out new versions of the website to support the 3D view facility, not good for me, but good for other non aviation enthusiasts. The App and website have been showing a few anomalies all day. So different versions of their databases linking to different versions of their website / apps at different times ! Hopefully all will be back to "normal" errors tomorrow
