Just installed Tapatalk myself and all working fine. I'm not sure we can do much more to help DuchessConstance, it sounds like it's device related.
I've tried on both my phones plus had a look on my partner's phone, so it's not the device - I think I must just be searching wrong or in the wrong place? I open the Tapatalk ap, click Following, then search. This is what I see: i67.tinypic.com/2ywgtfq.png
I'm waiting to hear back from Tapatalk help desk. I've been using Tapatalk for a couple of years so I know how buggy it can be. It's fine though, I don't mind using my laptop.
I just wish to really thank you all who organised this transition and managed to keep our community together. Unfortunately I wasn't able to help with anything, but I was completely blown away by the way everything was conducted; the efficiency, the democratic, and civil, discussion on how to best proceed, the great ideas, and that absolutely brilliant summary provided by John_Rebus. John, may a thousand fantastic productions of Newsies pop up in every capital of Europe. BurlyBearR, Matthew, and all those whom I'm not mentioning because I have a sclerotic mind, thanks for all your work in securing a new, safe home for us. I wish I could erect a statue for all of you at the very centre of the West End.
