Salesforce Winter '21 Release

Due to Salesforce does not support the Private Browsing mode (Incognito) in Lightning Experience, do not use this mode in any browser when working with the following:

Activity Report
Calendar
Change Request
Quizzes
Template Editor
Related Lists
Buttons
- Mass Managing (Account or Contact) Targets
- Add Selected to Event

Otherwise, set up third-party cookies to use the CT Mobile package features in Lightning Experience via the incognito mode. For example, if you are using Google Chrome, follow the instructions here.
