5. press the suggested email.

Actual results:

Hi,
I do not see any other (and simple) way than use setInterval() function. I searched for some libraries which can help us to avoid the issue but I noticed that all of them are using setInterval() function internally.

I decided to not include any additional libraries because fix is pretty simple... Hope it's ok.
