[juans-chainsafe]

Describe the bug
When you try to use Ramp samples in main or the ramp sample scene, Ramp starts loading but is stuck in that loading spinner forever.

Steps
Steps to reproduce the behavior:

1. Use the scene [SampleLogin - Metamask or SampleLogin - Web3Auth]
2. Login with [Web3Auth or Metamask]
3. Click on Try Off Ramp or Try On Ramp or Try On/Off Ramp button

Expected behavior
Ramp main screen appears after the loading spinner

@juans-chainsafe is this only on 2022? is it working on 2021?

Is working in main that the version is 2021, and its failing in #938 that is using 2022

This is actually a Unity issue. You can find more information here

Workaround for this in Unity 2022 can be found here: #938 (comment)

We're working with Ramp for a possible fix in the meantime please upvote the Unity issue here

Please use this workaround in the mean time:
Ramp issue on WebGL can be solved by doing this:

1. First make a WebGL build NOT Build And Run
2. Second use this command to start a web server for your build "C:/Program Files/Unity/Hub/Editor/2022.3.26f1/Editor/Data/MonoBleedingEdge/bin/mono.exe" "C:/Program Files/Unity/Hub/Editor/2022.3.26f1/Editor/Data/PlaybackEngines/WebGLSupport/BuildTools/SimpleWebServer.exe" "[Build Directory]" 60606 make sure the directories match yours
3. Finally navigate to http://localhost:60606/index.html

In Mac second step should be replaced by:

1. Install python
2. Change "Compression Format" to "Gzip" in Publishing Settings
3. Enable "Decompression Fallback" in Publishing Settings
   
4. Run python3 -m http.server in the build folder
5. Go to http://localhost:8000/index.html in the browser
