how to deposit xmr on bittrex

[birr]

I went to the deposit page and generated an address and payment ID.
I am using a tablet.
The copy function is screwed up when I try to long press on the payment ID to highlight it.
The number only stays highlighted for about half a second.
So I quickly hit copy.
But when I pasted the payment ID in the wallet I was transferring the xmr from, it pasted something else entirely, a snippet of code or something.  I kept trying.  Eventually a google page appeared that said "your search did not match any documents" and showed the payment ID, which I was then able to copy.  I entered the transfer in the originating wallet.  OK.
But now I have another problem.  The Bittrex xmr deposit page is stuck on that payment ID.  There's no way to make it generate a new one.

Maybe I did something wrong?

maybe you must wait until a few confirmation because usually if we want a deposit that need least 10 confirmation not instanly

Support says tx ID is supposed to always stay the same, so that explains that.
But I'm having problems making bittrex and poloniex work in mobile browsers.  Bittrex doesn't work in Chrome browser for Android, for the reason I posted.  I thought of trying a different browser, and it turns out bittrex works in Dolphin.
But poloniex is almost useless in all the browsers I've tried, Chrome, Dolphin and Opera mini.  Just putting in a couple of trades takes as much as half an hour.
