Funimation is a very secure site. On two occasions, they did not let me in under the pretext that my credentials were not valid, although I know for sure that they gave 110%. Maybe because I used a VPN. Try going to a site with your real IP address, especially if you live in America. Keep these premium accounts because they are hard to find. In fact, it is better to start with a basic plan. I posted 1000 of them.
Please, before you reply to a post, look at the date it was posted. Don’t expect several accounts to run for more than five to seven days and sometimes shorter. Just saying
