App is too slow with Lookups

[powerapps890]

I made an app that uses lookups from the datasource for mostly everything. The problem is my counter outside the gallery which uses a label is based on Checkbox selections that are also based on a label. When a box is checked or unchecked it is immediately patched or removed from the datasource. The problem is that this causes a lag of multiple seconds sometimes. If I were to uncheck a checkbox it would recheck for a second then go away. If I were to check a box my counter would similarly go up down then up to the correct value. The app is taking too long and sometimes crashes because it is too slow. How can I fix this?

My first suggest would be to store the gallery options in a label inside a collection when the app starts.  That way the data is on the local device (fast!!!) and does not need to be called from SharePoint.  When the form is ready for submission you can PATCH the data back into the datasource.

What is gallery options? I am not sure how to implement what you are describing. If needed I can post my code. @mdevaney

Sorry, There is not anything called gallery options.  I was referring to your checkbox options which I presume are stored in the items property of the gallery.

I am a little confused..Yes in my items there is a checkboxcolumn. So what can I do? The patching is way too slow this will not work what I dont get is why it works well with radio buttons. @mdevaney
