My guess is that it’s more likely that the Creator Center is having issues for you here than 0.00% traffic. If I try to look at any of my stats on the Creator Center with a range of more than 30 days, it comes back with 0 for every statistic.
I’ve sent in a request about it and they let me know that there’s too much data for that range and the server is timing out, resulting in 0’s for everything. They said they’re working to fix it and should release a fix soon. This might be the issue you’re seeing instead of 0% traffic (especially seeing that you have 40k+ downloads on it)
As for getting ‘back’ into recommendations, I’m pretty sure the MW algorithm uses similar algorithms to social media where old content just phases out of being promoted. With hundreds of new models daily, that’s just how it’s got to be I believe.
