I am sorry, probably I am just completely out of it, but then how does the guy in the video do it? Is it a fake video?
When I follow the exact same process (and this goes for the original OP too).
1. Create an app in [....]
2. Sharepoint (phone layout)
And then when we enter the site URL and then type in the list name, we get the ''Cannot read property 'tableName' of undefined'' error. But I am doing exactly the same as the guy in the video, who makes an app. I gave you the timestamp.
I guess my brain works in a different way as I am not by default a technical person, but I have successfully worked with Office 365 and Powerapps. My question is simply: why does this work for him, and not for me, and why does everyone on the internet answer this question by just talking about something else? That's not a knock because I definitely appreciate the help. But I just don't understand.
What am I supposed to do?
