Why do I face TinyMCE issues in Apptivo?

TinyMCE is a collection of miscellaneous plugins. You can find the TinyMCE, a rich-text editor found online as an open-source software available. This accesses the text area and fields in the Apptivo App in all platforms and automatically moves on the cursor to the text area while entering the email of the recipient. This is in no aspect the shortfall of the Apptivo App instead the result of Grammarly enabled in your browser.
