How to repro:

npm install
npm run start

Fonts don't load, and I eventually get an MD5 mismatch error:

[Unhandled promise rejection: Error: Downloaded file for asset 'babysweet.ttf' Located at http://192.168.1.55:19000/assets/assets/fonts/babysweet.ttf?platform=ios&hash=7c9263d3cffcda46ff7a4d9c00472c07?platform=ios&dev=true&hot=false&minify=false failed MD5 integrity check]
at node_modules/expo-asset/build/PlatformUtils.js:53:18 in _downloadAsyncManagedEnv
at [native code]:null in flushedQueue

This seems to happen with any .ttf font I try...

A few things to note:

• We get a MD5 mismatch on the fonts.
• the URL includes /assets/assets/.. which looks maybe incorrect?
• Font URL seems malformed (two ? in the query params):
  • http://10.103.48.232:19000/assets/assets/fonts/babysweet.ttf?platform=ios&hash=5751ffa9c86291f684a5d30b67814476?platform=ios&dev=true&hot=false&minify=false
• What's also strange is manually manipulating the URL quickly seems to work
  • manually modify the URL to the following: http://10.103.48.232:19000/assets/fonts/babysweet.ttf
  • remove the f from .ttf causing an legitament 404 in the metro server
  • quickly restore the f, hit enter and you'll be served the font
