This looks like it will be fixed in an upcoming release

I tested using our nightly
https://blog.xamarin.com/try-the-latest-in-xamarin-forms-with-nightly-builds/

And we should have a 3.2 pre-release out soon that looks to also have this issue resolved

Hi, looks like this has bug is a regression, it was working up until 3.4

4.2.X

It's even worse in 4.3-pre3 where even the normal text stopped responding to the set FlowDirection
4.3-pre3

I am still having the problem on iOS devices

[Elashi]

Any news about this issue?

@Elashi are you having issues with RTL for just the FormattedText on iOS, or also for the normal Label?

[Elashi]

I have issues with RTL only when I use <Label.FormattedText> and only in iOS

[sjorsmiltenburg]

@Elashi do you have a workaround?

[Elashi]

Yes, not to use <Label.FormattedText>. I just use multiple <Labe>s instead now.
Instead of using one single big label with a lot of <Span>s in it , I use multiple <Label>s
Actually , <Span>s have another problem. If you add Tap gesture handler to it, it will not catch it if you tap on it, you have to tap bellow the actual <Span> to be handled correctly.
do NOT use <Span> !
