Did you try ENBDX? It's their new app, looks very good.I use ENBD priority banking for 7 years. Yes it is working but don't expect good customer service also their website/mobile app is outdated. They have good credit cards like Skywards and Marriott.
Mashreq has a very modern website and app but again decent customer service.
ADCB has the best customer service in UAE but the website/app is a little bit outdated.
