Whenever coming back to Reddit—whether that is from locking the screen momentarily, clicking on a link and then closing it, etc… my location in the thread is lost. It almost always scrolls up 10s of comments. This happens every single time while inside of a post.
Further, this will happen on the main screen viewing posts as well. It will scroll up a few posts and you’ll have to scroll down several to get back to the same spot. Or, and more annoyingly, it will refresh and you’ll lose where you were completely. This seems to be the same bug in the locked iOS refresh thread that was supposedly closed/fixed in most recent update. There is no update in the App Store so presumably I am on the most recent update.
This will happen within 30 seconds after moving screens so shouldn’t be due to running out of memory or anything like that. I’ve got a 17 Pro Max so Reddit should be fine in the background if I open a link in Safari and then swipe back after a minute or two. But almost always it will refresh. Or if my screen auto locks (30s) and I unlock less than a minute later, it will refresh the Home Screen.
