Like the user below, I have a Lenovo Chromebook. I can't reply to or forward an email. All I get is a blank compose screen. I followed the steps to fix this in the help section that you posted - which I found insulting. I had done all those things before I came here to find a fix. This is hurting my business. My Pixel 4xl has been sent in for replacement, again, & the Google warehouse has lost it, so I am working on a loaner phone that can't handle email. HELP?! Send an update please.
