iOS 9 is pretty out of date, so it may be one of the issues. Do you have any other devices to test on?
Can you screenshot what you see?
It works on my desktop computer. I don't know how to do a screen shot. All I can tell you is where there is supposed to be a picture in someone's post it says " attached thumbnail " and in "garage" at the top of the page when you click to see someone's pictures the text is there but where the pictures are supposed to be it's just blank.
You my have too many apps running at the same time, and don't even know it, and your iPad is a little overwhelmed. LOL. See if this helps:
Make sure you do not have a lot of apps running in the background in the iOS App Switcher.
Double click the Home button to check this.
Keep active App Switcher Apps to a minimum. For older iPads (iPad 2,3, 4 or 1st gen iPad Mini models running iOS 9.3.5), 20 or less active apps should be fine. Ideally, 6-8 or less active background running apps, in the iOS App Switcher, is even better!
If you have a lot of apps still active, tap and hold a finger on one of the apps and slide your finger up to quit the app.
If you can reach another app with another finger, you can quit more than one app simultaneously.
Also, turn off iCloud services if you are not using them. Turn off bluetooth if you're not using it.
Clear the cache in your browser.
After closing the apps and making other above changes, do a hard restart to be sure all the apps are cleared from the memory. Hope this works for you.
