I'm unable to see the lists of posts I've made on desktop, mobile, and any of the mobile clients I've used. This goes for my accounts on both sh.itjust.works and Lemmy.world. I like seeing how my posts are doing or going back to read comments on there even if they've been marked as read. Could it be that it's not showing my posts because they've been marked as read and I've got settings to hide read posts? If so, seeing my own posts should be exempt from this setting.
UPDATE: if I show read posts, I can see my posts. This is definitely something that should be fixed; show read posts settings should only apply on my feeds, not when I'm looking through a user's or my own post history
Faced similar issue today.
