Is it socially acceptable for females to drink alone?

I (36F) am visiting CDMX solo in February, staying in Roma 4 nights and Napoles 4 nights. I like to go out and have a nice beer or a cocktail, not with dinner and not to get drunk, I just like to sit in a bar and have a drink or 2 with my own thoughts/phone. Not looking to go to clubs or out late at night, not looking to meet anyone but will people think it's strange if I go to a bar and drink alone? I read this article and now I'm feeling nervous that I'm going to draw negative attention https://hispanicexecutive.com/hisplaining-drinking-alone-in-mexico
