Having just graduated from Maple 9.5 to Maple 2016.2 I am flummoxed by
the simplify command. My expression includes square roots, and all I get
from simplify is "`simplify/sqrt/product` uses a 2nd argument, n, which
is missing" which is of no help at all. One would think it would use the
old simplfy procedure (eg assuming positivee argument and positive
result by default, or something like that).
Looking at the help page and putting in
simplify(%,assume=positive) just give the same response.
If simplify is simply going to throw up its hands in despair every time
it runs across something slightly out of the ordinary, it makes it
pretty useless.

Why not give us an example where you get this message?

Error, (in simplify) invalid input: `simplify/sqrt/product` uses a 2nd
argument, n, which is missing
In the sequence of calculations I an doing, stuff like this can occor
all the time.
simplify(sqrt((1-2*m(u)/R(u))*R(u)^4));

In Maple 2015 I get...

Let's see what happens in other versions.

So, it looks like it is bug introduced into 2016.2 (maybe earlier).
