Metagrid Pro MIDI faders

Using MG Pro 1.6.18 with Cubase 15 on Windows 11. I just tried a few MIDI faders and the input is noticibly “lagging” as much as 2-3 seconds behind input from the fader. The MG fader can be moved instantly, while the cooresponding control in Cubase moves slowly to the new value in a few seconds. This didn’t happen previously, but since I haven’t used the faders in a while, I don’t know which update may have caused this. A mechanical fader via USB doesn’t display this problem. It was the same over USB or Wifi. It seems like a stream of data, such as cc data from a fader, is choked a bit. Perhaps a buffer gets too full or something like that. Regular macros and single commands are not visibly affected.
