Hi,
So you need someone to fix errors in your zaps. I have been using zapier for more than 2 years now and i can help you with your problem.
I develop chatbots and they often require zapier integrations, that's why i have hands on experience on zapier. I have read all three of your problems and i can help you with them.
Give me a text so I can start solving your problems. Looking forward to hearing from your side!
Regards,
