I am using biblatex and I am trying to put a comma between the author and year.
If I use
\parencite{GrandViewResearch2019}
the result is
(Grand View Research 2019)
instead of
(Grand View Research, 2019)
I have tried the different solutions proposed in this post, but unsuccessfully it didn't work. Maybe the command has been changed since 2013?
