strange widget behavior
While running my iOS widget I discovered that it sometimes shows a strange background screen with Cancel/Post button and a textfield. I attached a screenshot, my widget should be empty but contains the Cancel/Post screen.
I can reproduce this behavior on my iPhone (6 with iOS 10.3) by executing the following steps:
- Go to widget screen
- Then press the Search area on the top
- Then press cancel
- Now the widget shows up with this Cancel/Post area as a background.
In the simulator I can sometimes reproduce it (1 out of 10 times) but still I will always see it flashing in the simulator and then disappearing quickly after doing the steps above.
Is this screen something build in in the Xamarin platform ? How to get rid of it ?

VS solution to reproduce bug
Very simple solution to reproduce behaviour
Hereby a link to a small movie of me reproducing it on my mac simulator after a few tries:
Any news on this ? Are you able to reproduce ?
I just upgrade to VS 15.3 and I still have the problem.
I was not able to reproduce with the sample you provided. Could you provide detailed steps on what I should do with the solution to see this issue?
OK, please do the following:
1) Run the solution on iPhone 6 simulator (not s) or iPhone 6 real device.
2) Goto today screen
3) Add solution widget as first widget on today screen
4) Now on today screen click in search area at top
5) Now press cancel (returning to today screen), sometimes you see the widget flickering with the cancel/post buttons and then recovering, sometimes the cancel/post buttons stay on the widget.
6) repeat steps 4-5 a few times
On real device it almost always fails on simulator 1 of 5/10 tries it fails.
Please let me know if you can reproduce ?
Any news on reproducing this ? Because this is still a big showstopper for our app.
I was able to reproduce this with the steps provided in Comment 6.
## Regression Status
Does not appear to be a regression.
Hi! What's the status of this bug please? I experience the same issue using iOS 11.2.6 and the current stable versions of Xamarin Forms and Visual Studio 2017. Is there any workaround to prevent this behaviour?
Just checked the default code that is generated when adding an iOS Today Extension project.
Problem is that TodayViewController class inherits Social.SLComposeServiceViewController. Replacing that with a UIViewController and doing a complete solution Clean + Rebuild fixed the problem.
