Hello, I currently have an app published to the App Store. Today, I updated XCode on my laptop and did a build. Now, the production version of my app will not open. It just goes to a black screen, then crashes. I suspect the issue might be caused by Firebase/Crashlytics, but I have no idea how to debug this. When I load up a build using XCode, it works fine. It is only the production app that is crashing. I've attached a crash report file. My app is called "Tracking" and uses CloudKit, with Firebase/Crashlytics. I've had issues like this with Crashlytics before where it crashes on launch, but with this being in production I'm not sure how to debug it, and I would like to be able to fix it without having to push out an update. Please help! Mike Tracking-2021-10-03-190232.ips.beta.crash

Hi, I have a relatively new app up in the App Store. I dropped the price recently and was happy to find that I start getting ~1 user entering into a trial each day. However, as those users start to come to the end of their trial, I've found that almost all of them have ended up with a status of "Had a billing issue" followed by "Had their subscription cancelled due to a billing error". Out of 8 users who have entered the trial period, 7 ended up in this state, vs. 1 who cancelled the trial before it was up for renewal. Is it possible that 7/8 of my users have used invalid card info when subscribing, or did I set something up wrong? I tried signing up using my own phone and it went through fine. I am using the RevenueCat SDK.
