New iOS app

Hi!
I recently got an apple watch and wanted to try WaniKani on it. For some reason, the watch app did not automatically appear, so I tried to reinstall the iphone application itself.
Unfortunately now, when I try to open the app I am greeted with a message “Shiba recognised you! Wait for him to do his magic…” but Shiba seems to be lost…
I have let him do his magic for 10 minutes straight, but to no avail.
There seems to be few people in the thread recently who encountered login problems. If you could take a look at them, I would be very grateful.
