Just to confirm that in my case (O365), this happens all the time.

Hi Christophe,

Thank you for your comment, I was thinking I had made this issue happen somehow (very big form, many rules etc) but I've just tried a new form and the same thing occurs, also in O365.

Emily I will get onto that now, thank you for your advice.

Hi Andrew, this happens all of the time for us as well (O365). The 'flash' of the form panel appears prior to the entire form loading.

Likewise, we see exactly the same sequence on O365 form opening.

Cheers,

G.

Hi everyone,

Quick update from Nintex, the problem doesn't seem to be anything I've (we've) done on the form, which is good news. Here is the response I received so far from Nintex support:

"Due to the nature of the cloud environment, it is
difficult to advise a method for avoiding this time delay. On every Form
opening there are certain actions that require communication with the Azure
server that have to be communicated from your own tenancy through to
Microsoft’s Azure environment that is based in the US. This can result in
extended loading times during form rendering dependent on the current load
across all aspects of communication channels and environments.

The delayed loading times is being investigated by Nintex
product development team and we are looking at ways to resolve this. As soon as
we have found a solution to the delay times we will be sure to let you know.

I apologies that I am unable to offer you a direct
resolution for this issue and thank you for your understanding."

So if anyone is looking to fix this issue themselves at the moment it doesn't seem like something we can do ourselves just yet. But as Cameron posted Nintex are still looking at this for us.

Thanks Cameron McConnell​

Andrew
