Google Play Console says internal test is available, but it's not

The answer is that 48 hours may be considered typical, but my internal test was not ready until a full week after its upload to the Play Console. During that week, I put in a ticket with Google developer support, but never got a response. My recommendation is to wait for a week, and then put in a support ticket if it's still not up by then, and hope they respond.

Same issue - our app wasn't available after 48 hours, so I reached out. I quickly got this reply, which is unfortunate:

Hi, Thanks for contacting Google Play Developer Support!
Please note that your app submission to the internal test track is still processing which is the reason it's not accessible via it's opt-in link yet.
Due to adjusted work schedules at this time, we are currently experiencing longer than usual review times. While the situation is currently evolving, app review times may fluctuate, and may take 7 days or longer. Moving forward, we recommend you adjust your planning to account for this and avoid resubmitting, as each update or change to your app will cause the review process to start over from the very beginning. We understand the inconvenience this may cause and thank you for your patience and understanding. If you have any other questions about using the Play Console, please let me know and I’ll be happy to help.
Regards, Suraj Google Play Developer Support

Wow! I am on day 4 now and my app is still "being reviewed"... The Internal Testing Url is still not working... My app got rejected because of some wording in my description that violated their content policy. The reason for rejection was very vague and didn't say what it was. I cleaned up anything/everything including the term "youtube videos" and saved it. So when they emailed me the "rejection" email (Day 2) I went and checked the Google Play Console and it still said being reviewed and didn't mention anything about the rejection... Google needs to overhaul that entire system because it is virtually un-usable! They may as have have used white text over a white background! Geesh!

My iphone app review process with Apple was done in 2 days! Much better experience!
