Created attachment 8529277 [details] payment-screen-loading.png This shows the payment window in its state where no assets have loaded, only HTML.
Created attachment 8529279 [details] payment-not-loading-dmesg.txt Maybe this sheds light on what happened?
ferjm, since we caught a dmesg this time is there any information to go on?
This is worth looking into because it seems like a bug specific to the Trusted UI.
I can't see in the logcat or dmesg anything related to payments or the trusted UI.
Just chatting to didem, it appears to be failing only in the latest builds? An old build from November was working just fine? Need info'ing Didem so she can correct me on that.
One theory is that our CDN is unreachable in some way causing no assets to be loaded. See bug 1103025 for precedence.
You may be able to verify this theory by checking the network requests and responses with the WebIDE connected to the device.
Yes, I saw this issue in one of the recent builds (a build released before the week of Thanksgiving, can't remember the exact build id). I didn't see it in a build from September, and I did not see it in builds from December.
I've been doing extensive testing while working on bug 1097928 with a mock payment provider and I didn't see this issue happening a single time. This looks to me like a connectivity issue with the CDN as mentioned in comment 10.
