Because I think written words already explain it all. It's just simply captcha error. But as you requested, Check the image below. It goes like that and sometimes image is slow to reload when it available after couple of refresh.
Go to Settings > [your name] > Password & Security, then turn Automatic Verification on or off.
Interesting. I think this might be the problem. This problem persist after I save my account password on my browser when it ask me. Thanks Lucius! I will give this a shot tomorrow. My Ipad already got drain just now.
Can you tell us what exactly IOS gadget you use when trying to load the captcha?
Also, tell us what version of Safari browse.?
And maybe you are trying to access the forum with an outdated IOS device or Safari.
I search a bit and it looks like the Safari browser has some bugs related to the captcha like slow loading or captcha that doesn't load properly.
So I think this is not a forum issue it's your device issue that might need to be fully reset or it needs to be upgraded to the latest version.
I'm using Ipad pro 11" 4th gen, I'm currently running on latest iOS and Safari browser.
Sometimes when I login to a mobile browser and wanting to login to web device I do face difficulties on less I logout from initially log places before I would safely login to my web browser. Although sometimes it automatically logout then I have to login back again. I will suggest you to try use chrome browser sometimes I found it very easy in passing captcha verifications.
Yes, I log in both on my mobile, ipad and desktop which I use alternately depending on my mood or workplace.
