Magento 2 - Order email - template override not working

Question

I need to style the items table in the order email.

So I have copied

/vendor/magento/module-sales/view/frontend/templates/email/

to

/app/design/frontend/[Vendor]/[Theme]/Magento_Sales/templates/email/

Added some content, ran my script that fixes most of the "issues"

rm -R ./pub/static/*
./php bin/magento cache:clean
./php bin/magento cache:flush
./php bin/magento setup:static-content:deploy --force
./php bin/magento setup:static-content:deploy sk_SK --force
./php bin/magento setup:di:compile
./php bin/magento indexer:reindex
./php bin/magento cache:clean
chown zonemediadev.sk:html ./ -R

note: ./php is shortcut to php7 because the server by default has php5 on cli.

I have re-sent the order email from admin, then manually triggered cron. Then I have received the email without the added content.

If I add content in the /vendor/....../templates/email/items.phtml then it works fine.

Also I am receiving the same email multiple times (from 2 times up to 11 times) Why?

Any suggestions why the override does not work?

Answer 1

Well, on the next day it started working. Probably some buggy background cache.
