Installing DNN Platform in Azure Website

I was installing DNN Platform on an Azure Website following this documentation on DNN website. But, for whatever reason, my installation never finished and stopped at 18% and gave up. The log button shows nothing. Trying the "Retry" button produces SQL error for basically trying to create existing DB elements.

So I proceeded to delete my website and its DB - and try again from scratch. But after 2-3 times trying and getting the same result over and over again, I started to dig into the internet and found this post - which basically saying:

After installing the website and prior to installing the DNN platform, change the scale from "FREE" to "STANDARD" on your website. Stop & restart - and then proceed to install DNN.
