This all began when I saw Grammarly giving me a red line on the verb has. My sentence, as I remember roughly, was...
Social media has all potential to make your products and services popular
The Grammarly tool suggests 'have' and gives me a reason:
The singular verb has does not appear to agree with the plural subject media. Consider changing the verb form for subject-verb agreement.
It gave me surprise because I have, at many places, seen the usage of Social media is... I then explored on OALD which has an entry for this two-word word
social media (uncountable, plural) ~ Social media is a big part of my life
Kindly help me learn.
