+about: Report a bug in FLEX
+title: ''
+labels: bug
+assignees: ''
+
+---
+
+### Environment
+- Platform+version: **iOS 14** <!--- Change to match your platform and version -->
+- FLEX version: **9.9.9** <!--- Change to the version of FLEX you're using -->
+<!--- FLEXing / libFLEX users: please include FLEXing and libFLEX versions separately -->
+
+### Bug Report
+
+Here, you can provide a description of the bug. Some tips:
+
+- Please do not paste an entire crash log. Upload the crash log to something like [ghostbin.co](https://ghostbin.co/) or another paste service. Alternatively, you can cut out the relevant stack trace and paste that inside a ` ```code block``` `
+- If the bug is more complex than "this button is broken" or a crash, consider including a sample project. For example, if your app's requests aren't showing up in the network history page.
+- Providing steps to reproduce is always helpful!
+- If you want to include a screenshot or GIF, consider modifying the default markdown for uploaded images to use this code to make the image smaller on desktop:
+  ```
+  <img width="50%" src=your-image-url >
+  ```
+
+This template is a suggestion. You may format your issue however you want, but generally you should at least include your iOS version and FLEX version.
