I just upgraded to the 13 Pro today and couldn't get my A10 to connect. I knew that I had read something on here about it and found the post. On the A10, I kept trying to add an Audio Device and nothing would work. After reading this post, I played with some settings and what did work for me was going into Bluetooth>REC Remote. There I saw my old device in the Manage Added Devices. I decided to try the Add Device (Pairing) from there and lo and behold, the bluetooth device was finally recognized on my phone and I'm all good to go. Now, I didn't look up the A10 directions, so maybe this is how it is supposed to be done anyway, but like I said, I was trying to pair the device from the Audio Device menu. Which was wrong.
Just thought I'd add to this.
IMPORTANT FOR iPHONE 13 USERS
I've had my A10 for one year and it's been my main recording deck since the day I got it (previous main deck was an Edirol R-07). I used my iPhone 12 Pro Max when I first got the A10, and I've been loving the ease with which I can control the recording with an app on my phone. A week ago, I got an iPhone 13 Pro Max (w/ 1TB storage). And that's when this conundrum began ... no matter what I did, I could not get the iPhone 13 to recognize (and pair with) the A10. I tried and tried and tried ... but no dice. The only saving grace was that the iPhone 12 / A10 combo has always worked just fine, so I was still able to 
two shows last week while using the A10 app on my iPhone. But I only have two weeks from receipt of the iPhone 13 to return the iPhone 12 and get the guaranteed refund for the trade-in. I chatted with Apple support via text at their webpage ... not much help. I drove over to a Best Buy and found a sharp young guy in the smart phone section and he actually gave it a really good effort (especially considering I didn't buy the phone or recorder from Best Buy so I was just a random guy walking in off the street asking for service). After that, I finally decided I had to go big, so I made an appointment at the nearest Apple Store, which is an hour drive away. I don't go there often, so I don't know what's normal, but I was seen after waiting 5 minutes or so. The person who assisted me was a young lady named Grace, probably in her mid-late 20s. She dove right into it - had my iPhone 12, iPhone 13 and A10 layed out along with a few other devices of her own and also had the A10 manual pulled up on her iPad. For a good half hour she poked around through the iPhone menus, ran diagnostics, did various other testing, went to the backroom a couple of times ... but no bueno. She called her boss Sasha over and he worked on it for five minutes or so. He had some really insightful ideas for fixes ... but even he couldn't solve this. Sasha got called away to another customer and Grace went back at it. Around 45 minutes in - after reading parts of the A10 manual - Grace started taking a hard look at the menus in the A10; in particular, the Bluetooth menu. And then she found something and BANG - just like that - problem solved. So the smart thing for me at that point would have been to ask Grace exactly what she had just found that fixed the problem. But I was super happy to finally get this saga done with and this was 50 minutes into the session; and I could tell Grace needed a break. So I just thanked her and left. Just as she was about to solve the problem, however, I do remember her saying she was looking at the bluetooth settings in the A10 and it looked like it was set to send data out to a device like a bluetooth speaker, as opposed to being set to receive data from a recording rig. So after it was all said and done ... there is still that mystery out there ... if the bluetooth settings in the A10 were the problem (with the iPhone 13), for the last year, why (how?) did the A10 work just fine with the iPhone 12? Grace was equally baffled by this question.
TL;DR: If you upgrade an iPhone that works properly with the A10 app, but your new iPhone doesn't connect over bluetooth with the A10 app, the solution is probably in the A10's bluetooth menu.
