Bugfix/fix edge (#53)

## Problem

`process.nextTick` prevents the client from working in edge environments

## Solution

Commented out `process.nextTick` for now. This may cause text to break.

## Type of Change

- [x] Bug fix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
- [x] Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] This change requires a documentation update
- [ ] Infrastructure change (CI configs, etc)

## Test Plan

Manually testing the client.
