Thanks for reaching out and bringing this to our attention. Sorry to know about the trouble this has caused you. I would love to look into this for you.
For your first issue, your account is registered in Houston. Would you like to drive in Maryland instead of Houston? And since your account is for UberEATS, which only do delivery, TNC license and sticker is optional. But if you want to do trips, that's the time you will need a TNC license.
Regarding your vehicle insurance, please upload it again because we need to see your name indicated on the document.
Your immediate response is well appreciated. Should you have any other concern and suggestion you may also find this link helpful.
