I can no longer log into the app or its sister app Aqua. Not very good when trying to manage my account. (Hi Mera, I eventually managed to get back onto both apps this morning without the need to uninstall and reinstall. I've never experienced the aforementioned difficulty before as I always managed to log in simply with use of my PIN code, but the app was asking me to provide my username, etc. Anyway it's sorted now.)

Hi Stephen We are sorry this is happening. Please try uninstalling and reinstalling the app and/or updating the software on your device. It may also be worth using a different device to see if the issue persists. Hope this helps. Mera
