Is it possible to force a WaitPage to refresh at a particular interval?

Longer background: I have an app with a WaitPage. The WaitPage uses after_all_players_arrive to compute payoffs for a given round. The subsequent page has a timeout. I regularly encounter the problem that participants get stuck on the WaitPage while the timer already runs, meaning that participants time out even though they can only see the WaitPage. Manually refreshing the browser tab loads the subsequent page. 

One solution suggested elsewhere (https://www.otreehub.com/forum/852/) is to implement an auto refresh on the WaitPage. Is that possible, and if yes, is it possible to control the interval at which the WaitPage refreshes?

I am running into the same issue as well. Participants arriving early are stuck on the WaitPage while the last arrival are automatically moved onto the next page. The issue is resolved only when the early arrivals refresh their browsers. Did you find a fix?

Sorry for not replying earlier. I didn't find a direct fix -- in my case, I resolved this by getting rid of dependencies on numpy and pandas, but I have no idea how if at all these were related to the issue.
