+### 2. Verifying via reCAPTCHA doesn't work if both Signal and Signal Beta clients installed when setting up as standalone
+
+#### Steps to reproduce
+
+1. Get told to verify by captcha
+2. Complete captcha in Google Chrome
+3. Dialog prompt will tell you to click to open in Signal app, but captcha doesn't complete properly
+
+#### Steps to solve the issue
+
+1. Enter phone number and click "Send SMS", (opens the captcha link in your browser)
+2. Verify using the captcha
+3. Once it is verified in the browser, you will get the "xdg-open" or "Open Signal" dialog prompt
+4. Ignore the prompt
+5. Right click on the "Open Signal" hyperlink below the verification box and copy the link address. You should see something with the format with the format of `signalcaptcha://signal-hcaptcha.Foo-bAr_baz.challenge.fOo-bAR_baZ.fOO-BaR_baz...`
+6. In a terminal window type `pnpm start` space and then paste the link address from the previous step, ie.
+   `pnpm start signalcaptcha://signal-hcaptcha.Foo-bAr_baz.challenge.fOo-bAR_baZ.fOO-BaR_baz...`
+7. This command will open the `signalcaptcha://...` url with the currently running development version of the app
+8. Execute the command, it will say something like
+
+```making app single instance
+quitting; we are the second instance
+Done in 0.67s.
+```
+
+9. You can now go back to the original terminal session where you first ran pnpm start, you should see something like
+
+```
+{"level":30,"time":"2024-01-28T08:07:14.558Z","msg":"challengeMain.onRequest(standalone registration): received challenge request, waiting for response"}
+{"level":30,"time":"2024-01-28T08:07:40.974Z","msg":"handleSignalRoute: Matched signal route: captcha"}
+{"level":30,"time":"2024-01-28T08:07:40.974Z","msg":"challengeMain.handleCaptcha: sending captcha response to 1 handlers"}
+{"level":30,"time":"2024-01-28T08:07:40.975Z","msg":"challengeMain.onRequest(standalone registration): got response after 26415ms"}
+```
+
+This means that the development app has now accepted the Captcha challenge.
+You should now get an SMS to the phone number you entered earlier with the verification code. Enter the code and click "Register" and you will now be registered as a standalone device as desired.

 ### webpack
 
 Some parts of the app (such as the Sticker Creator) have moved to webpack.
