There are many indian citizens like the domain investor, who does not use a smartphone because she is a trained engineer who is aware of the risks of using a smartphone , being always connected to the internet with her main phone number, making it easier to hack the mobile.
Yet indicating the intolerance of the amazon team, Amazon is not allowing login to business account for basic mobile users since March 30, 2021
It is asking the amazon user to click on a link to login
In the basic mobile there is no option for link clicking, so the user cannot login
Amazon should realize that the real customer does not use a smartphone with her main phone number, if they do not change their software/login options, the customer will not purchase on amazon
