For several weeks I've had an issue following notification links to threads in emails.

For example, clicking on the link (phone, desktop whatever) takes me to that thread and the most recent unread post. When the thread is updated, I get another email alert but if it's a busy thread or I take my time to open it and I access it from a different device than I did the last time, I'm not taken to the most recent post. Sometimes, I could be taken to a point earlier in the thread, to posts I've already read.

Today, for the first time, the issue occurred when using the same device.
