I'm baffled Wilco. My very first problem was that I was using an old link to the site that existed for a long time, but was finally dusabled. Once I had the correct, newer link, everything was OK for a while. And I also stopped seeing that re-direct thing.
Now, I have no idea. First it changed on the phone, but my tablet worked fine. And I had started using my tablet more often because, as you said, the size of the phone makes it hard to navigate. But now accessing on my tablet is doing what the phone did a while back - old looking format, jumbled up tabs, etc. And the reply box doesn't show up on the tablet page, I have to type this on my phone.
Access and passwords also make no sense. As mentioned above, the fact that I'm signed in doesn't always match what the board is displaying.
