How to change Dynamics 365 CRM web interface from UCI to Classic version?

Recently created a Dynamics 365 CRM 30 days trial version (Ref: How to Setup Dynamics 365 30 days Online Trial version?) and it was navigating to CRM home page showing the list of UCI Apps, instead of showing CRM Classic Web UI.

Below is the screenshot for reference.

Later found that, the rendered URL was showing differently in the browser and having forceUCI and pagetype parameters.

If you want to see the old Classic Version of CRM, just use the parameter forceClassic=1, instead of forceUCI=1 and remove the parameter pagetype=apps in the URL and final URL will be like the below,

https://CRMOrgName.Region.dynamics.com/main.aspx?forceClassic=1
