I always access the Shard either from my phone or my computer. For literally 2 years my computer stayed logged into the Shard on its own. During the past week, I have noticed something odd occurring. Whenever I use my phone to look at the Shard, it logs me out on my computer. Whenever I use my computer to look at the Shard, it logs me out of my phone. I always click the “remember me” box. Is there an explanation for this?
