@Anonymous , thanks for letting me know. Saves me a lot of energy and potential frustration. Any change you found a suitable alternative for creating basic online forms which are publically available and for which results can be stored in an SharePoint Online list?
Nope, we don't have a need to rely on having the info public, so we are making due with allowing users to create items from inside of SP. Not the ideal route, but for our use, and with us not wanting to waste our time with MS support, it's the best we can do at this time.
