We have two calls for inbox canvas app, initialize and submit. the calls require you to respond within 3 sec or else it throw an error page (as it take too long to respond). Is it possible to send a loading page and response once the response is ready. Or is there a way to overcome this issue which requires to respond within 3 sec?

Hey @akhilesh j, I'd recommend chatting directly with our Support engineers through the Messenger about this - they'd be best placed to advise you here 👍
