Okay, so as you might be able to tell, I'm new to e621. I've already favorited about 100 things, but only about 70 of them are actually showing up. By any chance, would this have to do with the system I am using? Will they show up on PC?

I don't use mobile, but on PC, I can see all (as of this post) 83 of your listed favorites just fine. Do you have anything in your blacklist? Blacklist will hide posts even if you favorite them.

I was able to find all 98 of them by turning off the blacklist.

This might be stupid, but have you checked both pages of your favs? ([next] at the bottom of the page)

use status:any in your favorites search; could be they've since been deleted

None of them have been deleted.

My best guess is that it is a blacklist issue.

Okay, so below <search> you should see the text <Blacklisted> and then a number. What is that number?

Also could you link the last post that you can see? you seem pretty new so I'll tell you how to:
either you find the post ID under <statistics> or in the url and type post #[ID], or you just copy-paste the url into your post.

Hope this'll help ^.^

I’m on mobile and can see all your favorites, what system you use doesn’t matter. One thing that no one has said is that it might be your internet. Maybe? I don’t know. When my internet is slow sometimes it will only display some of my images. I usually just refresh the page and it fixes that. I feel like its either going to be that you didn’t realize there was a second page or that the missing images are blacklisted, though.

Nothing on my blacklist at all! It may be my device, in that case.

Wait a minute! Update: All favorites are back, somehow! For some reason, the next page button wasn't there. Thanks for everybody's help, though! Apologies for any inconveniences I may have caused!

I've also had issues with favorites dissapearing (and no they were not deleted) off my list, but they don't come back until I manually re-favorite them
