Chrome: >6 GB of data used overnight from a background process

[Android Central Question]

Woke up to multiple messages saying my data was out and I'm getting charged for new data. Found that Chrome rapidly used (vertical line in data usage) over 6 GB overnight, and I believe it was still doing it. I shut off background permissions. Never happened before, but I'm also usually on wifi. There were only 4 tabs open and all were old and static. Any ideas on why this might have occurred? I hope Verizon will be nice and understanding and give me my data back!

Sale happened to me yesterday. Is there a way to see what chrome did?
