RevenueCatUI.PaywallError 3 Issue


Forum|alt.badge.img+2

I have set an offering as default offering. When starting the app for the first time the default offering is loading correctly. After this I always get this error. The new default paywall I use is Paywalls v2. I do not try to load different offerings in my code just the standard default one. In Xcode I get the following warning

 

WARN: ⚠️ Failed looking up localization, using fallback: en_DE

WARN: Could not determine price format because price string is incompatible.

Hi ​@phil_byk,

I used your API key and bundle id in my sample app and I could populate your paywall correctly. Would you mind sharing which version of the SDK are you using and how are you fetching the offering?

 

Best,

Hi Joan,

The SDK version is 5.24.0. I use the PaywallView in SwiftUI without any special offering l. Just the default one. Currently it seems to be stable again. 
 

I test the app on real device by installing from Xcode. Sometimes it would work and sometimes I would get this error. When fresh installing on device it seems to always work but when I reinstall when the app is already installed I get this error or the paywall wanted to fetch an old offering I already deleted. I triple checked if I specifically fetch that offering somewhere in my code but I’m only using the default offering.

I think I found the issue: when I change the app language in the Xcode scheme, the paywall sometimes fails to load properly.
