Hi all, I have just powered up my A&K SR15 and connected it to Wi-Fi for the first time in ages (due to lockdown -not been out so no need to use it!). It has the pre-loaded Tidal app to which I subscribe, however, it wont let me log in. It keeps saying "Authentication failed Unknown error" although I have checked my login details thoroughly. Funnily enough, I have the Tidal APK side loaded for downloads (which I need to update as I see there is a newer version) and this lets me stream and play my downloads OK from Tidal. Any ideas? All other Tidal instances (this laptop, Bluesound Node2i, Android phone etc) are logged on and working fine, just my A&K SR15. Help appreciated.
