Just wanted to make a dedicated thread for this. The apps we have are currently not working. The company that develops these apps is aware of the problems and is working on a solution.
I'll update this thread as needed with any future updates.
In the meantime, if you are on a mobile device, this new forum software has a great mobile theme which might load automatically when you access the site through a browser on a smartphone, otherwise you can change the theme on the bottom left of every page.
Rest assured, we'll either get the app fixed ASAP, or I'll simply dump these developers and we can have a replacement app for both Android and iOS as soon as Google & Apple approve it. Just please have patience for the next few days while we try to get the current app up and running on the new software.
