Hello! It sounds like you're having trouble receiving a registration code for Aunio. Let's work through this together to find a solution.

First, can you let me know which email address you are using to register? Also, could you check your spam or junk mail folders to see if the code perhaps ended up there?

Here are some common steps that might help resolve the issue:

1. Check Your Email: Make sure that the email address you've entered is correct and that it’s the one you want to use for registration.

2. Network Connection: Ensure your iPhone is connected to a stable internet connection, either Wi-Fi or mobile data.

3. Try a Different Browser: If you're using Safari, it might help to try a different web browser, such as Chrome or Firefox, and see if that allows the code to be sent.

4. Resend the Code: Sometimes attempting to resend the code after a few minutes can help.

5. Check Blocks and Filters: Ensure that you haven't inadvertently blocked messages from Aunio or set filters that might prevent these emails from reaching you.

If you've tried these steps and are still having issues, we might need to look into it further. Would you like me to check if there are any known issues with Aunio's registration process right now?

They ask for a phone number on the app not an email and it’s just not sending me the authorization code. There is no option for email.

Thank you for clarifying that the registration process is requesting a phone number and not an email. Let's handle the issue of not receiving the authorization code via SMS.

Here are a few things we can try to ensure you get that code:

1. Check Phone Number: Please double-check that the phone number you're entering is correct, including the country code if needed. Sometimes even a small error can lead to issues.

2. Network Connection: Make sure your iPhone is connected to a stable cellular network and that you're not in an area with poor reception, as SMS messages can fail to be delivered in such situations.

3. Block List: Verify that you haven't accidentally blocked the number from which the verification code is sent. This could prevent the code from coming through.

4. Disable Any VPN: If you're using a VPN on your iPhone, try disabling it temporarily, as this can sometimes interfere with SMS delivery.

5. Restart Your Phone: A simple restart can solve many issues. Sometimes, just rebooting the device helps to reset any network connections.

6. Wait a Little Longer: Sometimes, SMS delivery can take a bit longer. If you've only waited a minute or two, it might help to wait a few additional minutes and then try to send the code again.

If you've tried all of these steps and are still not receiving the code, it may be worth checking with your mobile provider to ensure there are no issues with your account receiving SMS messages. Would you like me to check if there are any known issues with Aunio's SMS delivery?
