Heads up: Using All-In-One Migration with SMTP Mailer plugin presents extra step to work properly

I recently had made a new "template" on a fresh WordPress instance and slowly migrated my sites to it to ensure consistency (I know I could have done it manually for each site but didn't want to, lol). While I did a bunch of visual tests to ensure the sites still loaded correctly and everything, I discovered one issue today... the SMTP Mailer plugin (the new one included in WordPress) doesn't seem to work well when using All-In-One Migration (and migrating plugins with it too, perhaps might not be an issue if excluding plugins from migration).
The issue I discovered was an authentication issue when I ran the "Test Send" function in SMTP Mailer plugin. Going to the app details > Location tab and hitting Save without making changes, fixed the issue as it recreated the necessary data for SMTP Mailer to function successfully.
I suspect it migrated the old password over with it which caused the authentication issue.
So just a friendly reminder that if migrating websites via All-In-One Migration (which still works beautifully) and are setup with the SMTP Mailer plugin, you'll want to do a App > Location > Save action after the migration to ensure that it's all setup.
I didn't test but presumably this wouldn't be an issue if excluding plugins from the migration process.
Good luck. Hope the above helps.
