Yes, a fading was recorded 2020 April 26-29:

Unfortunately I noticed it only on 2020 May 3, but
nevertheless I informed some IP observers about it.

Such (brief) dips have been observed in a few other
intermediate polars, too (e.g. DO Dra).

Long (and deep) fadings have been observed in the
intermediate polar V1223 Sgr:

  There was a short fading episode to <16.9g around
2020 Apr. 28.  The episode would be too short to be
regarded as a VY Scl star.
