LTIs not launching correctly under Resources tab

Community Explorer

We are noticing some strange behaviors for some LTIs with a course nav access built into the LTI (namely LinkIt and MyLab and Mastering that we have seen so far) within C4E. These are both integrations we had installed previously and appear on the course navigation menu normally in Classic Canvas. We have noticed that both of these integrations do not open or function the same way when they are under the Resources tab with C4E. We are working with both vendors on these specific integrations because it's new to them as well and I plan to open a support ticket with Canvas directly about this, but wondered if anyone else was seeing similar things in their C4E course navigation specific LTIs?
