Yoroi not sending - silence from support

I have been trying for 3 days to send ADA from my Yoroi to my exchange to do my business. Yoroi opens, goes to send page, reads send address, accepts quantity but when I click on “continue” then, in Charles’ words, fcking nothing happens.
I have sent 3 mails to support but only get the auto response that they have received my request - and again, fcking nothing happens!

if it is an emergency you can use adalite.io to restore the wallet and perform transactions
