@wangzhi0417, which extension are you referring to? This GitHub repository is intended for bug reports in core Magento modules, in case of problems with some third party extensions their respective vendors should be contacted instead.

I also in trouble with this issue for 2.2.4. I found that it’s missing sender informations. I test on 2.2.5 branch , it works. I use mageplaze smtp extension. Just setup x
debug yesterday. Will try to get why it doesn’t get correct sender information today.

@kingyond Thanks, do you know when 2.2.5 will be released?

[wangzhi0417]

@orlangur I am using mageplaze smtp extension, thanks for the reminder, but I cannot find a place to discuss that extension.

@wangzhi0417 I don't know when 2.2.5 will release. I were in trouble for a month with version 2.2.3 and 2.2.4 release. Look like 2.2.x release cannot using as live commerce site. There are many bugs for these versions.

@wangzhi0417 Also, i confirm this bug cause by 2.2.4 itself. But not cause by mageplaze smtp extension. I am waiting 2.2.5 release. But had to consider using version 2.1.x . Really wasting time for 2.2.3 and 2.2.4. I think that should not be set flag as release version. Really not friend to new magento user. It's jump into trap after using version 2.2.3 and 2.2.4.

@wangzhi0417 I found a solution how to fix this bug.
open this file
vendor/amzn/amazon-pay-and-login-magento-2-module/src/Payment/etc/di.xml
find this line #63
<type name="Magento\Framework\Mail\MessageInterface" shared="false" />
remove the shared string
<type name="Magento\Framework\Mail\MessageInterface" />
save it.
after that, remove generated data and compile the di again. this should fix the bug.
rm -rf generated/metadata/* generated/code/*
php bin/magento setup:di:compile

If the above step not solved the problem.
try to fully clean the cache and run fully deploy
php bin/magento maintenance:enable
redis-cli flushall
rm -rf var/page_cache/* var/cache/* var/view_preprocessed/*
rm -rf generated/metadata/* generated/code/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile
composer dump-autoload -o
php bin/magento setup:static-content:deploy zh_Hans_CN -f
php bin/magento setup:static-content:deploy -f
service varnish restart
php bin/magento cache:clean
php bin/magento cache:enable
php bin/magento cache:flush
chown -Rf nginx:nginx *
php bin/magento maintenance:disable

@orlangur: that amazon module is now part of Magento 2.2.4 by default, so Magento has some kind of responsibility to deal with bugs introduced by those modules I think (even if it is only passing the information around that bug on to that particular vendor).

But luckily, for this particular module, there is an open source repository to report these issues: https://github.com/amzn/amazon-payments-magento-2-plugin/
@kingyond: would you be so kind to report this issue to that repo? And maybe even send in a Pull Request?

This also sounds like a duplicate of #14952, but I'm not 100% sure...
