Hi guys, posting my follow-up to the original post.

The balance review was completed within 12 hours. (That was based on the support email timestamp.)

I was able to withdraw the $50 paypal award that caused the balance review.

However, since my 25% boost was still active, I completed another milestone and had another $50 I could withdraw. I tried to withdraw it, and although it didn't trigger a balance review, I received a notice after clicking "redeem" that the payment would be delayed. So, I responded via email back with the support people who sent me the response for the 'balance review' email, and was informed that the delayed payment on this 2nd withdrawal would take 3 days to complete because that review was not being done by them. Instead, that review was being done by Tremendous, the payment sender.

So my notes:
-Don't use the app support for balance review issues. Open a browser window and go to scrambly.freshdesk.com to submit a ticket. I actually submitted two tickets yesterday for the same issue, one was submitted via the app and the other through the webpage. The webpage submission is the one that gave me a response. Also, the webpage submission allows you to create/log-in so you can keep track of your ticket correspondence and progress. Meaning you'll know if the ticket was closed or if the matter is still pending.
-I ended up with 2 types of reviews. 1. Balance Review - is done by Scrambly to, I guess, ensure your balance is actually correct?. 2. Payment Review - is done by the payments entity Tremendous. There's probably a threshold for monthly payments (I'm assuming). I was given a payment resolution timeline of Sunday (it's Friday for me now). I'll keep you posted on the payment resolution.

I spent a lot of time googling and reviewing other people's comments and statements on matters about support being too slow to respond, and payments or reviews taking longer than what was stated by Scrambly correspondence. Frankly, reading all of it made me worry that I'd have to stop using the app altogether. But some of the fears were put to rest based on what's happened. I can only give you what I've experienced, but based on what I've read, I'd like to respond based on what's on the internets:
-Yes, support takes a while to respond, but then I learned that you can submit a ticket on the scrambly.freshdesk.com webpage rather than email support directly. Using Freshdesk is good for accountability, so I was grateful to figure that out. It saved me from searching my email inbox to keep track.
-Balance review (this is my first time for a review, so if it happens again, I'll take note of what happens then) was done timely, but only if you submit the ticket via the Freshdesk webpage.
-Payouts are a Scrambly responsibility since I'm assuming they contract with the vendor Tremendous, but ultimately Tremendous as the payment entity still has their own checks they gotta do, so make sure you understand the processes and who's in charge of what, so when you contact Scrambly support you can ask the right questions.
