I've had two payments go through since the filing, so the operations appear unaffected.
I only just saw this referenced in a WSJ article today and their article from the time of the filing has this nugget:
Cash remained tight in February and Plastiq laid off 85 employees and contractors, reducing its workforce to 128 employees. It is now down to 45 full-time workers.
In what universe does a business like this need 100-plus FTEs?
