Since a few weeks we have users reporting that LTI links won't open in Safari. Upon clicking the link a new window opens and is closed immediately, the user is thrown back to the page where he initially clicked the link. Apparently Blackboard is aware of this issue for a while now, see https://blackboard.secure.force.com/btbb_articleview?id=kA339000000L6Q2 (though our test suggests it never works, while the article suggests inconsistent behavior). For illustration purposes a screencast is attached.
Blackboard recognized the problem but does not seem too worried to resolve this issue soon. Any more institutions running into this problem?
