I configured Oauth2 in Google Cloud Platform Console (created the
token/key pair ).

Then I configured Evolution to us Oauth2 for both sending/receiving
email with StartTLS after connecting set.  Everything was running
smoothly, minus the daily headache of the initial connection in the
morning and then again about 8 hours later.  (this account is still on 
pop with login/password).

So since 14/6/19, I haven't been able to connect with Oauth2.  When I
do get an error message it is the "Failed to authenticate: Data source
“<email address>” does not support OAuth 2.0 authentication" message.

I saw some issues in Bugzilla that suggested it might be related to bug
in the version I'm using so I built the 3.30 version of the flatpak
based on the info on the Evolution-flatpak page.  Same failure to
connect but NO error messages or dialogs.

DISTRIB_ID=LinuxMint
DISTRIB_RELEASE=19.1
DISTRIB_CODENAME=tessa
DISTRIB_DESCRIPTION="Linux Mint 19.1 Tessa"
NAME="Linux Mint"
VERSION="19.1 (Tessa)"
Linux 4.15.0-52-generic x86_64

Same architecture and kernel versions on both boxes.
