I am using the assets optimisation feature in Hummingbird, with files hosted on your CDN. All works fine, except that after some time (usually a week) on websites using reCaptcha, the file that loads reCaptcha becomes void, resulting in an error.
I am not 100% where the fault is, but I suppose that Google loads some extra files from some dynamic urls, therefore the CDN files are no longer accurate.
The issue gets fixed every time by clearing Cache.
It would be great if there was an option in Hummingbird to remove individual files from being uploaded to the CDN, and still being served from their original source!
Another annoying error, on websites using the Page Cache in combination with the Assets Optimisation, every one week or so, all the files hosted with the CDN fails to load!
