El Capitan released in 2015, last update in 2018.
Something is wrong with your resolution or other settings or browser if you cannot see the dropdown.
The dropdown from your name only goes down about 1/2 way vertically on my screen with 1920 x 1200 resolution.
So if the dropdown cannot be seen, then my guess your screen resolution is not enough.
most ipads are only 1024 x 768 resolution, but perhaps yours is higher, for further help, need to know the model (you have to look this up on how to spot the different models)
First, try zooming out with your browser, and again please state the browser you are using
Next, try a different browser.
After that, your ipad may be too old...
Since the change to the forum software, it may have caused glitches, the forum trys to understand the resolution of your screen, but the iPad can send goofy information in this case and misinterpreted by the forum.
tablets exist in the "no mans land" between phone apps and resolution and a real computer.... sorry...
