HELP Please... Has Anyone Hacked a Vincross HEXA Avoiding the App?

I have 4 Vincross HEXA robots (3 bought used and I repaired them).

The frustrating aspect of HEXA ownership is that they only function via the Vincross HEXA App and there must be a link established with the Vincross Servers in order to operate.

Apparently, Vincross is having financial issues and their Server reliability is spotty at best.

I would like to have control of these robots without the App being required.

Has anyone hacked a HEXA or can give me some advice?

Thank you for any assistance or input.
