I have the exact same problem, have contacted the developer on AppStore and reported a bug on website and just seems to have been ignored, stated on last update that app hasn’t been abandoned but quite clearly has. Should refund all purchases and make a free app if you aren’t going to fix the problem, I think it is shocking, there was an issue with the api and it was working again on inara in a couple of days yet here we are with a paid application that still doesn’t work, that is why I think it has been abandoned, if not then don’t start too many projects if you can’t keep them all going
