G’day Mate,
Thanks for the reply. I think I know what the problem was. I was resetting my username and I accidentally put in my old username. A notice came up saying that the username was already taken, however it showed the username with the first letter in uppercase. I went back on the app and tried putting in the first letter as upper case- it worked and I am now logged in on the app. Hopefully this info helps resolve the issue for those experiencing problems logging on.
Many thanks and all the best for the new year to you.
