Anyone have a fix?

Zoho on my Android tablet, just past few days will not allow me to get to the upper portion of the screen. It is the ONLY site I have trouble with. No other problem on internet sites with tablet, just Zoho. I can't scroll up to reach other folders or buttons, send, account, anything. I can scroll through some of the emails only. Attachment shows as high as it goes to top.

I have tried logging off/on, closing the browser, turning off my tablet and restarting, clearing history, etc... NOTHING helps.

Does anyone have an idea of what to do or why this is suddenly happening??? I can go onto my Android phone fine, but it is small & limited, not easy to use regularly & doesn't have the necessary info I need to answer emails on it.

Highly frustrated. Wrote to Zoho, no word yet - and they are usually good getting back to me.

(Zoho app and mobile zoho do not have the availability of features and ease of use the regular site has.) 

Thanks for any help.
