I experienced this on my instance on just regular desktop browsing for a while, so I don’t think it’s necessarily an issue with your client; it did eventually just go away on its own (somewhere around the time the instance backend updated, I’m sure), but I also found that switching on “show hidden posts” fixed it as well, and since I don’t really have any hidden posts it didn’t make much difference. Downside was I had to do that manually every time, but it did at least get me to the second page.
Yeah unfortunately I’m not terribly familiar with this client, I just wandered in here from - and I hate to say it, given the circumstances - the second page of hot, so I’m not sure what all options you have available, but if the button’s there that might fix it.
Now, it does look like your instance is running version 0.19.5 whereas mine’s on 0.19.6, so it’ll probably be fixed once an update goes through, whenever that may be.
