It works for me. See below.
library(hts)

my_ts <- replicate(4, arima.sim(model = list(c(ma = 0.8)), n = 12))
my_hts <- hts(my_ts)
#> Since argument characters are not specified, the default labelling system is used.
forecast.gts(my_hts, h = 4)

I get the following error for a hierarchcial model with only two levels (i.e. top and bottom level) if I try to apply the forecast function to an hts object: Fehler in utmat %*% fcasts : non-conformable arguments Zusätzlich: Warnmeldung: In cbind.Matrix(x, y, deparse.level = 0L) : number of rows of result is not a multiple of vector length
I'm relatively sure that this code still worked about a year ago. The error does also not occur for a hierarchie with 3 or more levels.
