This is happening yet again.
When a model is added to your Favorites, the "heart" icon is activated.
Yet, when you refresh your screen or come back to the site (of course after refreshing), the model is NOT in your favorites section but back down below in the general section

How to reproduce this?
- login
- see the models' section view (NOT YOUR FAVORITES SECTION)
- add model as favorite either by clicking the hamburger on the top right of the preview icon OR click into the model's room and add favorite that way
- close that model's view, go back to Favorites section, see model is not there
OR
- add the model as favorite (HOWEVER YOU WANT)
- logout from the site
- log back in
- see favorites area (model is not there)

I don't know how much more info I can give you. If this isn't enough, please let me know.
And YES, in this test case it is assumed the models being added ARE STILL ONLINE. Hence, the expectation that they will appear in MY favorites section after being added as a Favorite. Quote

We have tested both methods you mentioned but we did not find any issues as the models remained on our favorites list. We will still have our dev team look into this but at this time we did not find any issues. If anyone else is experiencing the same issue please leave a response here so when the dev team looks into this they have more information to pull from. Quote

It's happening again. I cleared cookies for the site, logged in again and still happening.
It doesn't matter which model.
This was happening about a month ago and I reported it to Customer Service. It appeared to "fix itself"....however this time it's been a day or so. Quote

And now miraculously the expected models added to favorites are appearing.
If you pushed a fix, thank you
If not, we have more investigating to do haha Quote
