From WD:DEV:
I have universal log in, whilst logging in to my en Wikipedia account, I noticed two items that needed to be linked at ko Wikipedia and zh Wikipedia. Using the edit links button on both I received a message that I needed to log in here which I subsequently did. However, on returning to the pages I still received the message that I needed to log in. I rebooted and refreshed the pages and still I got the error warning. This is a problem with Chrome running on Android KitKat 4.4.2. I tried it with my device's other factory supplied browser (unhelpfully called Browser) and that worked
