Help: MIT App Inventor Fusion Tables Error 401 Unauthorized Invalid Credentials

[Nicole Meister]

I created an app to have others input their information and then it would hopefully show up on the fusion tables. In October when I created this app, it was successful. However, now when I came back to it, there is an error 401 Unauthorized Invalid Credentials. I've tried creating a service account but that is also unsuccessful. Even when a user who has access to the google fusion tables on google drive cannot enter their data and have it successfully show up on google fusion tables. What is the issue? Any help would be beneficial. 

Is this an issue with google developers console or is it my issue?

It does not look like you have used the forums yet, as a search using the search box above would have returned several threads about this topic.

for some devices, the api key method unfortunately does not work anymore, which results in "error 401 Unauthorized Invalid Credentials"

MIT is aware of that issue, see also here https://groups.google.com/d/msg/mitappinventortest/zasQRzYA4H0/_dqtmT4DCgAJ 

Meanwhile you can use the service account method instead

After I tried the service account, I encountered a different error. Are you sure that service account works? If it works for others than I will try it again.

Thank you.
