I am having an issue here with an existing CNAME, it seems that it is resetting it's self on a daily basis. Do I need to adjust the TTL? Is there something I am missing? if someone could assist that would be greatly appreciated.
I'm not aware of any issues matching what you described. TTL shouldn't affect this. If you are trying to change some specific default records, such as WWW, they could revert when some changes are made to your domain name. If your domain name is not active or if there are some other pending changes, that could also be affecting your ability to change the DNS for the domain.
If you continue to have trouble with it, I suggest calling Support so they can take a detailed look at your domain name to investigate.
