When creating an email campaign, you are required to "save" your written email content before you can begin editing other sections in the email campaign. However, if the save button doesn't show it may be due to an ad extension blocking the button.
Not all extensions cause this to happen. The extension, Grammarly, is often the culprit. If you use Grammarly or have several Chrome extensions on your browser then that is most likely the reason why you are not getting the "save" button.
Here is how to fix it.
1. Play the simulation in an incognito browser.
2. Play the simulation in a different browser like, Mozilla Firefox
If one of those two options do not fix the problem then please email us email@example.com and we will help with your specific situation.
