WbizTool Questions

I sent an email a week ago regarding a question, never had a reply.
Sent another one, and still no reply.

I implemented via API and struggled a long time thinking my coding is incorrect and then I see my messages did sent via my api request, but is stuck in PENDING when I go to the WBIZ dashboard....
Is this a reliable way to implement API messages in my app for notification purposes....
Any help on why my messages is stuck in pending mode?

I have sent emails to vendor email wbiztool and also sent in the wbiztools help support but I never got an answer. Please help. it always said it go disconnected. However, I tried to reconnect it, sometimes it got the qr code, but when I can scan it, the wbiztool responded "Your WhatsApp connection is failed"
What should I do?

Is this service still supported and updated? Messages remain stuck as "Pending" for hours, and there is no way to get a response to any support inquiries.

Dear Wbiz Tool Support Team,

I am writing to report an urgent issue with the service.

Starting today, the system has stopped sending messages. In an attempt to resolve the problem, I tried performing a server redistribution. However, after doing so, the QR code required for login is no longer displayed.

The application now gets stuck in an infinite loading loop while trying to generate or load...
