[ARCHIVED] Permission or access blocked to some students on a Google Slide assignment

[Hook]

I published my google slides to the web, and then embedded the URL. Most students can access my google slide presentation without issue. Unfortunately, some students are getting a page saying they need to request permission or access. These students have gone through the same steps of authorizing their google drive account, but still get blocked from going directly to the activity. I googled it and the answer doesn't make sense unless all of the students were blocked. It said the URL was not embedded correctly. Is that (url embedding)  still possibly the problem, even if most students (all but 1 in one of my 5th grade classes) can access it? Hoping the fix is on their side and not mine. Nervous that taking it out and reentering it may cause an issue for other students on campus or remote users. Thank you in advance for your help.
