+## Shared Settings in Groups with Different Monitor Types
+
+With `CheckGroupV2` you can group uptime monitors (e.g. URL, TCP, DNS) and synthetic checks (e.g. API, Multistep, Playwright Check Suites). Depending on your plan type, some [group settings](/constructs/check-group-v2#configuration) (such as parallel runs or advanced retry strategies) may not be supported across both monitor types.
+
+To avoid conflicts, Checkly validates group settings against the lowest common denominator of supported features in the group.

+## Mixing Checks and Monitors in a Group
+
+When you purchase a plan in Checkly, it includes access to specific monitoring features. As shown on our [pricing page](https://www.checklyhq.com/pricing), feature availability can differ between:
+
+* Uptime monitors (e.g. URL, TCP, DNS)
+* Synthetic checks (e.g. API, Multistep, Browser, Playwright Check Suites)
+
+This means monitors and checks on the same plan may not all have access to the same features. For example: A Browser check might support `parallel` scheduling, while a TCP monitor only allows for `round-robin` scheduling.
+
+Groups let you organize any type of checks/monitors together and define [shared settings](/platform/groups#configuration). If those shared settings aren't supported by all monitors in the group, Checkly will throw a validation error asking you to either adjust the configuration or remove the incompatible monitor.
