We have identified an issue when the Grammarly addon is enabled whilst using the Splash Page Builder or Email Builder
Issue: If the browser add-on Grammarly is enabled it will inject code to support itself into the content blocks of the splash page. Testing has shown that this code has a negative impact on the performance of splash pages.(See example below)
Resolution: If your splash page has already been affected by the Grammarly add-on it is suggested you disable Grammarly and recreate the splash page. [ht_message mstyle="alert" title="" show_icon="" id="" class="" style="" ]It is possible to go through the content blocks and remove the injected Grammarly code. As editing the code can cause issues it is considered best practice to recreate the splash page.[/ht_message]Example of a content block that has had Grammarly code injected.
