I am having the same issue.
This was a money grab to build there new product and also put it on appsumo called adcreative which is why the site redirects to there new product now. Appsumo hasn't done anything about this. If you still want access to the platform it's unsupported with a link to login.
Same issue! Website is redirecting to AdCreative and Login not working
I am not sure why its redirecting but here is a log-in link I have that still works https://suite.adyouneed.com/authentication/login
ok thanks.... they are nowhere but still running?
Thanks buddy... They discontinued the site and won't be doing anymore updates. Once enough time has gone by they'll label it "out of business" and discontinue the login link as well, after all no more money is coming to support it. Similar to other tools that have come and gone without a trace but you'd think they'd replace access with the new platform to at least try to make up for this issue.
Sadly I hope that isn't the case but it's been a rough 4 years on this project that's for sure. They did just integrate AdCreative.ai in there when you are making the ads. Meaning you don't need an AdCreative account to use it. They added it as a additional feature. I also heard that AdYouNeed has such a bad name they are moving everything features wise from AdYouNeed into AdCreative. We'll see
