Hi I'm facing trouble in uploading the logo image in the transaction email section using admin back-end, it is still showing the previous one but with some block and the resolution showed "x". May I know the cause of this and how can I solve it?
1) Try to upload through Admin panel.
2) Try to upload through magento root folder.
php bin/magento c:c php bin/magento setup:static-content:deploy -f
