Wow... I thought I was the only person who discovered these "new" problems.
Yes, it does seem suspicious that you are the first person reporting the problem, but a "Tech Alert" really is the best way to go. This will require tech support to actually attempt to duplicate your issue and issue you a written response on what they found.
Of course, on the last one they sent to me they flat-out lied on the written response and I caught them red-handed. They said they tested a feature, but when I called them back and got a supervisor on the phone and MADE them go step-by step along what they said they did, they got the same error I had been reporting.
Unfortunately the supervisor took no action and wrote it all off as "an honest mistake".
