DescriptionWarning toast messages stay on screen until the user closes them, instead of closing automatically after a few seconds. This is most noticeable in Account Search, for example the warnings that appear when a search returns no results, when the results exceed the maximum number of records, or when no search field is specified.

Root cause:
In Spring '26 (V18), toast notifications across Medical Information Cloud were moved to the supported lightning/toast module after Salesforce deprecated the legacy platformShowToast event. Unlike the legacy event, lightning/toast keeps info, warning, and error toasts on screen by default until the user closes them. As a result, warning toasts that previously closed automatically now stay on screen.

Steps to reproduce
  1. Open or create an Interaction.
  2. In Account Search, run a search when the results exceed the maximum number of records.
  3. Observe that the warning toast stays on screen and doesn't close automatically.
WorkaroundClose the toast message manually by clicking the close (X) icon.
Fix versionSpring '27 (V20)Resolution notesWarning toasts are set to close automatically. Error toasts intentionally stay on screen until the user closes them, so that users don't miss an error.
