Stuck with a message that someone is sharing a file with me (the file doesn't exist anymore)

Thanks for the updates, felipera29! This behavior is quite interesting indeed. 

If you visit your All files page here, are you able to see this file on your end or does it keep showing only on your mobile apps?

Hello Nancy, and thanks for your support. I checked everywhere possible in all my folders and this file doesn't exist anymore. In fact, even when I try to visualize it by clicking on the notification that appears for me in the app, it says that the file is not available anymore. It is really interesting for me because I know exactly what file this is. It was an undergrad project that I did with this person in 2012. I am pretty sure I stopped accessing soon after and from nowhere this notification reappeared to me.

Hey felipera29, sorry to jump in here, but could you try clearing the app's cache and let us know if this message comes back?

I tried cleaning the in-app cache as well and it didnt work =/

Thanks for the update felipera29 

Would it be OK with you if we reached out via email to have a further look internally at this point? 

Yes, I would like that. This notification is annoying me and making it impossible for me to use the app.

Hi again, felipera29!

I just logged a ticket for you, so that we can look into this further. Please reply back to me, when you get the chance.

Thank you Nancy and everyone else for your support. I responded to the email earlier today and am awaiting further instructions.
