multi-domain no longer function?

[Arrmm]

I followed the guide and I can get the single domain, and even multiple domain to work great. However, I couldn't get the multiple-domain option to function despite many attempts.

On top of that, when I tried to run the console from the container, it doesn't even show the -m option when I tried ./namecheap-ddns-update.

Can anyone provide the correct syntax for the docker compose to run with multi-domain?
