have been trying to get miroBoard picker working for a while now. have submitted the app twice, and it was working for a while, but then it stopped. When we try to go ‘whiltelist’ the domain, it won’t let us → it says it’s an invalid domain, no matter what we put in (including localhost)

Been struggling for about 2 months now, have sent in multiple enquiries, but no response. have a paid account with 20 members. any tips?
