Looks like you’re using Safari version 12.
Yes and no. If you have an older model iPad, this may be the latest version of iOS offered for your device, simply because Apple has stopped supporting it. So, in that sense it’s the latest.
It’s not the latest version of iOS that Apple has released, that would be 14.7.1, with 15 coming out soon.
That said, this Discourse (our forum software) page does say that iOS 10.3 and newer is supported, so it should work.
I have an old iPad 2nd generation at home, like yours it’s stuck at some older version of iOS. I’ll see if I can dig it out tonight and see if it works, or if I can replicate the problem you’re seeing.
Have you tried accessing the site from some other device, just to see if the problem goes away then?
