I took another machine and loaded it up with  Linux Mint 19.1
based on Ubuntu 18.04 LTS
Linux 4.15.0-52-generic #56-Ubuntu SMP

I purposedly did not install the Evolution system build.

Then I installed the flatpak version.

I start the flatpak and have it load an Evolution backup as a starting
point.  The load succeeds with no messages in the terminal window where
I started the flatpak on the command line.

Shutdown Evolution.  Upon restart the flatpak version comes up and
pitches the following error.

   (evolution.bin:57): e-mail-engine-WARNING **: <time>: Failed to add
   service 'Sendmail'(sendmail): No provider available for protocol
   "sendmail"

In the error window with in Evolution shows

   Data source “<email>” does not support OAuth 2.0 authentication

for each account trying to use OAuth2.  Once cleared the messages never
reappear, yet the status icon in the account pane shows the connection
arrows with the red error indicator.

Both accounts are setup with 

   Receiving Email:
      Server:  imap.gmail.com  Port:993
      Encryption method:  TLS on a dedicated port

   Sending Email:
      Server:   smtp.gmail.com  Port: 587
      Encryption method:  STARTLS after connecting


Neither is successful at authenticating with the Gmail servers.
