For over 1 week now I've not been able to select all spam for delete on my iphone. There is no longer an edit option or select all option available
You won't be able to do it within the Gmail account. You will need to add your account to the pre-installed app called mail.
Goto settings, then select (Mail, Contacts, Calendars), select add account, then enter your email address and password.
Select your notification preference and then press save. You can add as many email accounts as you like. Once you add all of
your accounts select the pre-installed app called "mail" with the dark blue background. All of your email accounts should be there.
Select the desired email account then go to junk, select edit, then delete all.
