Hi Conor McCarthy and thanks for your report. Sorry to hear that slow speed has been making your work difficult. To make this more actionable, it would be great to get the appID of your app to study this further. The appID can be found from URL when your app is open in Composer. It would be also great to know if there is some particular operation where you see slowness, for example saving some particular page or is it possibly the app opening with preview app. Best Regards, Timo Kapanen
