I created iOS certificates in my dashboard in Ionic but I can’t remove them. Nothing happens when I click on “Delete”
Which dashboard are you talking about? There are 2 right now while Ionic migrates from the legacy backend to the new Ionic Pro (until Jan 18).
I’m using new dashboard
Ionic Pro is a hosted and closed source service, so there is not much we, the community, can help you with. There is a FAQ and common/known issues at https://ionic.zendesk.com/hc/en-us/sections/115003254647-FAQ-Common-Issues - but I think your issue is not one of them. You can - and should! - contact support at http://ionicframework.com/support#support
Can you use your browser’s dev tools’ network panel to see if it triggers a HTTP request and what their server returns?
