iPad Mini 2's not working with App anymore?

Hi. We have used our iPad Mini 2’s for years with the App. Working on Monday, then on Thursday - if you try and login to an account, the screen disappears, the app closes and you return just to the ipad home screen. Strangely, we can use the Gallery. Problem just arises when you try and login.
It is not a Firewall issue, as not working at home either and we’ve deleted and reinstalled the app as well.
Any suggestions much appreciated!

Hi @thinkbig thanks for bringing this to our attention, our devs are looking into this!

We’ll let you know as soon as we have an update. Thanks for your patience!
