I only joined today but I have a persistent bug I think.
So whenever I go to the tags menu at the top it logs me out and asks me to log in. I usually have he dark theme and it will change it to light..
If I select a tag though it will take me to that tag and I will be logged in and back in dark theme. But if I go back to tags menu it will ask me to log in and change theme. It has only done it on the tags menu up to now.
I am using safari on an ipad on ios7 if that helps
