I must admit to getting more and more confused by this.
I looked up the last two people I have messaged and both were last on RC either today or yesterday, yet both messages are still being marked as unread,
If they'd been marked as read but I'd had no reply, I'd just shrug my shoulders and add them to the long list of people who don't bother to reply. But, as they're shown as delivered (so presumably not read) I'm seriously wondering if the system is working as well as it used to. Why do these people insist on changing something that wasn't broken??? Do they no longer send email alerts? Are people just meant to notice the little number by the envelope sign at the top of the screen? I had a figure 1 on my 'envelope sign' for months but it was indicating a message I'd read and dealt with ages ago. No matter how many times I went into it in order to try and 'convince' Ancestry's system that it had been read, it took weeks before it finally disappeared of its own accord.
There doesn't seem much point wasting my time contacting people if they're not going to receive the message! I think I might email Ancestry with this , though that will probably be a waste of my time as well. They'll probably blame covid - everyone else seems to!!
