Hey @mimosa, When you do a quote, you don't have to put all the text even that your writing in it, just do the quote of what someone says, then write below it.
Do you have a Gmail E-mail Account?
I saw in the screenshot that said "Sign in with Google", you can try that if you have Gmail E-mail Account.
Also, did you have good WiFi? Sometimes it takes awhile to log in if there is not very much WiFi
