I created a trial instance of Dynamics Sales using my gmail address. I’m able to log into it, but I’m having trouble with creating customizations. When I go into Settings, I see a message “please use Power Platform admin center to leverage the latest experience and manage security settings”. When I try to log into Power Platform admin center, I get "You can't sign in here with a personal account, use your work or school account instead." This makes no sense. Why would I be allowed to create a trial instance of Dynamics using a gmail account, but not be allowed to use the same gmail account to customize the said instance?
In the same trial instance, I went into Processes and tried to create a Workflow using the old-style interface. There were no errors, but every step of creating the process was extremely slow. There was a message encouraging me to use Power Automate instead. I heeded this message and logged into Automate using the same gmail account. I tried to create an automation that would integrate with the trial instance of Dynamics, but could not do so because the Dynamics 365 connector was marked as Premium. It was also marked as deprecated, which is not a good sign. (There were additional connectors for Dynamics that were not deprecated, but they were meant for the types of Dynamics that are not Sales and they were all marked as Premium.) The documentation mentions that I should use the Microsoft Dataverse connector instead, but I could not find it in the Connectors section.
I also created a sandbox through mslearn.crm.dynamics.com. But this sandbox had no options for creating new fields or layouts, and no options for creating processes.
Is there anything I should be doing differently, or is there really no way to use Power Platform and Power Automate with a trial account?
