I have setup 2 moodles to talk to each other using LTI (3.1 as provider and 3.4 as consumer).
If the LTI course is set to open in a new window (on the consumer), everything is good. a new window launches with the course on the provider platform.
If I embed or embed without blocks, then the frame appears in the consumer moodle, but is always blank. Frame embedding is switched on in both moodles.
Any assistance appreciated......
