The occurrence is of the page timing is random, you just got lucky with the API not timing out for the past couple of days.
The engineers have a fix for it, just waiting verification and a deployment.
Just got word that one of the boxes that we test in, got destroyed some how during our colomove and we are in the process of getting another so that we can verify the fix.
Sorry Mark I know you and other love this feature, it will get fixed.
Thank you all for your patience.
It's been working beautifully for 2 days, updating regularly and no blank pages on automatic Refresh.
But that has just started again!
Has anyone been fiddling with the code?
