Option 1
You don’t know who your LiveMe agent is and how to contact him/her.
You can write me the ID of your LiveMe page, I will ask other agencies, maybe the agent will recognize you and get in touch with you.
If your agent doesn’t respond within 2-3 days, then I will cooperate with you.
Option 2
You need to create a new page on another device, make entries for Casting according to the Instructions, and after receiving an invitation from my agency you can enter your login and password on the old device and work through it.
If you don’t have another temporary smartphone, you can clone LiveMe app, your smartphone should support this function, Xiaomi definitely can, I checked. As a last resort, reset the phone to factory settings.
I explain why it is necessary
LiveMe has linked your agency account with your device, so you need another device and a new account to get an invitation from another agency and start all over again. Use a different phone number during registration or use your email instead of the number.
