+ SSO sign-ins and sessions are experiencing degraded performance Customers using Single Sign-On may have difficulty signing in to the RevenueCat dashboard or may have their existing sessions interrupted. This issue only affects organizations with SSO configured. RevenueCat SDKs, purchases, subscriptions, entitlements, APIs, analytics, and data exports are unaffected. The issue is caused by degraded performance from our SSO provider. We are monitoring the situation and will provide another update as soon as we have more information. No action is required from customers at this time.

+ Our SSO provider has identified the cause of the elevated error rates and implemented a fix. We are seeing sign-in and session errors decrease as the service recovers. Some customers using Single Sign-On may still experience intermittent difficulty signing in to the RevenueCat dashboard or may have their existing sessions interrupted. This issue remains limited to organizations with SSO configured. We are continuing to monitor the recovery and will provide another update once the issue is fully resolved. No action is required from customers.
