Microsoft adds reusable functions and a new layout container to Power Apps
The May 2026 update makes User Defined Functions generally available. Makers can now define a function once and call it across screens without repeating the same formula. A new Grid Container control arrived that lets controls snap into rows and columns instead of manual X and Y placement. An InfoPath migration agent also launched that converts legacy forms into canvas screens with one click.
Before this update every repeated calculation lived in multiple places. Changing one meant hunting through every screen and risking missed copies. The Grid Container changes the layout model from free placement to structured rows and columns. This reduces the pixel-by-pixel adjustments that currently dominate early builds, though delegation limits and formula scope still apply unchanged.
Analysis
Skip the migration agent until you finish one screen with the new Grid Container. Open your current app, drop a Grid Container on the main screen, and move three controls into it to see whether the layout holds when the screen resizes.
