Amex is really bad in recent weeks. Shell, Aral and Rewe used to work perfectly. For a few weeks now, acceptance has declined somewhat. Yesterday Shell and Rewe terminals completely refused Amex via Apple Pay and I had to use my physical card. It's starting to get really annoying.
My Visa and MasterCards work perfectly though as ever. I'm also very, very happy with the overall service and product with Deutsche Bank and glad I switched. Well deserved and the overall UX will be improving massively in the next few months due to the new APIs, apparently including instant push being integrated into the main app and lots of other cool stuff. I was debating getting bunq again to play around with (esp. because of the maestro card), but as Girocard support is incoming and comdirect is working on implementing their debit card (the VPay part), I think I'll wait for the developments this year... 2019 is definitely a great follow-up to a fantastic launch for Germany. Very pleased so far and can't wait for my remaining banks to launch. France has also seen many big additions (HSBC, BNP Paribas/Hello bank, La Banque Postale, ...) in the last few months, so it seems that slowly but surely Apple is gaining traction with the big holdout banks and countries. Will be interesting to see if Apple can fill the last gaps on the European Apple Pay coverage map (esp. Netherlands) this year.
