Hi all! I have a bit of a head scratcher here. I have a vertical gallery where the Template size is equal to the sum of three variables, shown below.

If I hover over these three values, I see that they are equal to the following

Unfortunately, despite this, the template size is still equal to its previous value

Obviously, 122 is not the sum of the three values above. Funny enough, once I take another action, like pushing a button in my PowerApp, the size does correct itself, but it's very Inconsistent.

This not only happens in the editing view, but also the preview view.

For extra context, title_projectName.Y and Description_Abstract.Y never change in this context. The only thing that cahnges is Description_Abstract. It changes from a value of 10 to 198 when I press a checkbox. This happens because A: Description_Abstract has autoHeight turned on, and B: its text is set to

If(Checkbox.Value, ThisItem.'Abstract Note')

Any ideas on why the template size updates so inconsistently, despite the values that it is dependent on updating consistently? Thank you for your time!

Is this possibly just a bug with power apps?

Update:

Instead of just setting the templateSize = to what I had before, I tried changing the onSelect of the checkbox to update a variable. I tried both Set(...) and UpdateContext(...). Both seem to have yielded the same results I've been getting...

From my perspective, it's as if the order in which variables and fields are updated in powerapps are effectively random, thus causing these inconsistent results. Is there a way to force a certain field to update last? If so, I could force the templateSize field to update its values last. As shown in the original post above, the .Height value of the abstract description is correct, and yet somehow the change is not reflected in the templateSize field. If the templateSize was updated last, then I suspect it would update correctly.
