My Zoho email won't attach anything

Hi

I have an issue where i can't attach anything with zoho mail. It doesn't always happen but very frequent. I did click the attach and picked the file. The attachment wheel came up then after it's finished the file was not shown there. I made attempts to reattach it but nothin happened. I did a trial and sent to my own email and yes the attachment was not there.

Could u let me know why coz this is really frustrating as I have to deal with clients and this causes a major delay.

Thank you
