Hi @mohammam,

Are you 100% sure that you're only using LTI 1.3, and don't have some old and forgotten about LTI 1.1 installs perhaps in a subaccount or even a specific course?  We removed the LTI 1.1 integration here after our fall term ended, and I have not seen that message anywhere myself, not have I had anyone report it to me (but that doesn't mean it's not being displayed somewhere incorrectly either).
