PowerApps form opening slow


We are using Custom PowerApps Forms for a SharePoint list. There are 250 fields in a SharePoint list of which we are using ~175 fields. Due to complexity of the form fields for different views where fields are at different places (vertical order), we have created 5 custom Forms. So based on the step the approval is in, we show the respective form.


There are also other related lists which items are displayed in a form. For example, document library with items related to current item. So overall there are many connections to different lists and libraries ~15-20 and the 5 Forms ( of which only 1 is displayed).


Now when we open the form, it is taking around 1-1.25 minute to open. We believe all the connections it has is making the form opening slower.


How can we make this faster? Is there anything like delayed connection so after the main form is opened we start connecting to other list/libraries? Also are the 5 list forms starts loading while opening the form page? We are changing the Visible property to show/hide the other forms.

If I understand well, you are dealing with a SP list with 250 columns ? Maybe I am wrong, but I am pretty sure that your data model is wrong.
But, maybe you should load data with concurrent function and split data into several collection.
