We have been trying to get this tool to work with Moodle 5 for a while now. The given documentation (https://learn.microsoft.com/en-us/microsoft-365/lti/microsoft-365-lti-moodle?view=o365-worldwide) not only has issues like naming the tool one thing, and then referring to it by a different name in a later step, but also seems to be missing some crucial step. We have followed the getting started guide, and the debug guides, and even reached out to MS directly, with no luck on guidance as to why we only get a generic "Something went wrong" page.
We are very excited about the capabilities this tool is designed to provide, and would appreciate any assistance available with getting it running in our environment!
