Hi all. New to Dynamics 365, but have been using and customizing/configuring CRM 3 and 4 since it came out. We are moving to Dynamics 365. I created a custom entity and necessary fields. When I go to the main form to start adding fields to the form, it will not let me. I cannot add standard fields that CRM created or any of the custom fields I created. It looks like it is going to let me drag and drop fields into existing sections, but it doesn't. I created a new section, but I cannot add fields there either. I have System Admin and System Customizer security roles. I know I will be embarrassed by whatever simple thing I am missing, but this is driving me crazy. I saw a couple videos that said you will see a red line in order to insert between two fields, but I never see that either.
Edit: BTW, I am using a 30-day trial, but I don't think that should make a difference. I also cannot add non-custom fields to any existing entities. In other words, I cannot do any kind of form design editing with fields. I cannot move fields that are already on the form either. HELP PLEASE before I go completely crazy!
