Can you give a specific example of a file that's not downloading?  Also, how did you request it to download?  Did you tap a link on a site, use a menu, or navigate to a URL through the address bar?

Alright, well the first file I noticed this with was a picture from Google Images of a BMW i8 that I was trying to send in a message (original image here: https://o.aolcdn.com/images/dims3/GLOB/legacy_thumbnail/800x450/format/jpg/quality/85/http://o.aolcdn.com/hss/storage/midas/b5d9afa0cf977556ad3a527db114725d/204197032/bmw-i8.jpg). I have tried long-pressing the image and clicking "Download image" from the Google Image search results, doing the same from the original image at the link above, and also by clicking the download button in the drop-down menu from the original image. In all cases nothing at all happens.

Thank you!  FWIW, I tested this on my personal phone and it worked for me after I was prompted to, and gave, Chrome permission to access local storage (Chrome version 61.0.3163.81, Nexus 5X, Android 7.1.2, Build N2G48C).  

I think probably the right next step is for the Android folks to look at it, which from c#4 I think is in progress.

I've tried messing with the permissions (Chrome had permission already when this started), to make that prompt appear. Even when it does and I grant Chrome permission to access/modify local storage it still behaves the same.

Unable to reproduce the issue in Android. Able to download the files from webpages.

@ianlantzy: Could you please clear the cache and browsing data of your browser and update your'e Chrome to the latest version and check if you still face the issue?

Thanks!!

I tried doing that again (I've actually done it about 5 times in total so far), it still didn't change the behavior.

ianlantzy@, Can you please go to chrome://net-export, reproduce the problem and attach the logs here? That will give us a better understanding of exactly what is happening.

ianlantzy@, friendly ping to provide a chrome://net-export logs to help us reproduce.

Closing due to lack of feedback. Feel free to reopen if you can repro and attach the necessary logs.

Sorry I forgot to come back and comment on this. After updating to version 61 (currently on 61.0.3163.98), the problem completely stopped. I'm not sure what was causing it, but the update to 61 seems to have completely fixed it.
