Where is the PLUX Biosignals Support and what happened to the Bitalino and the Biosignals Forum?

In the Biosignals support, there is only a knowledge base left:

https://support.pluxbiosignals.com/

We wanted to ask the support about the Biosignals Explorer:

it says it has Sampling Resolution: 8-bit or 16-bit per channel. Is it possible to have 4 channels with16 bit sampling rate live streaming in parallel at the same time?

But we could not find an option to ask this question.

We also could not find the Bitalino forum anymore. Also the Physioplux forum is gone.

We asked many questions there, and the links to these questions are dead.

The same happened with the Interaxon Forum.

If we are looking for an alternative, it is also possible to have 3-Lead ECG with OpenBCI Cyton or Ganglion Boards. If our target is InfuxDB and Python for processing data, the platform we choose is not so important.
