END misunderstood in MATALAB APP

Hi everyone
I have a matlab APP with a part like this:
if (dato1(end,6)==1)
trigger =1;
end
The problem is that the environment automatically thinks that the "END" in dato(end,6) is the one terminating the IF structure. As a consequence, the next end is taken by another thing in the code. This also happens in a while cycle where a statement like:
vector = vector2(end,:)
and that END is taken as the end for the while cycle.
The same code in a script works correctly obviously. Is this an issue of the app?
Thanks

I see similar issue in AppDesigner R2019b -- use of the end keyword definitely seem to confuse the parser.
The workaround would seem to be to use size with the appropriate dimension argument value and/or a temporary variable to store the appropriate value.
Looks worthy of a bug report to me.

Yes I indeed solved using dato(length(dato),1)

Hi,
I understand that clicking on the 'if' is highlighting the wrong end.
This issue is fixed in R2020a Update2.
