Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Essential enterprise features like Enterprise Connections and SCIM are not available on the Essentials or Professional plans.

   The pricing page explicitly states that users must upgrade to the B2B tier to continue using these features, creating a hard dependency on a higher-cost plan for standard enterprise integration needs.

2. 02

   The free tier requires credit card verification to enable custom domains.

   While the free plan is advertised as not requiring a credit card to sign up, the specific feature of using a custom domain is gated behind a verification requirement that contradicts the 'no credit card' promise for that specific capability.
