Yesterday evening, I´ve payed successfully my beer at a local cinema.
Today I wanted to pay a meal at a supermarket (which I have done a dozend times). Starting the wallet on my watch says: "Your wallet is empty".
Started Connect Mobile shows no card in my wallet.
So I tried to reenter the card information on Connect Mobile on my Android. It was declined with "Card is already in your wallet".
Starting the wallet-app on the watch again, showed "Synchronizing Wallet" for a short period of time and afterwards still "Your wallet is empty".
There was only a Connect Mobile Update involved since yesterday and today. The card just disappeared, but still is somewhere, so I cant add it again.
Mobile: Huawei Honor 10 (EMUI 9.1.0 | Android 9)
