The following limitations have been identified. When they are resolved, they will be reported in the latest [Product Updates](docId\:ctp96DP9fLvJm-PlRXE8K) under *Resolved Issues*.
| Description |
| ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **DeviceHub:**
* DeviceHub user role permissions cannot be modified after they are saved. As a workaround, remove and recreate the role. |
| **Analytics:**
* Manufacturing Connect Edge validates models only for archive format. Manufacturing Connect Edge does not verify that a model is loadable, or that the Input/Output operation names configured on the TensorFlow processor exist in the model's signatures. The processor saves without error, and any mismatch surfaces only as a load-time error when the source is enabled. As a workaround, run `saved_model_cli show --dir --all` to confirm the exact operation names before configuring the processor. Names are case sensitive and must come from the same signat
* FileReader processor is unable to read files that are generated from Flows Manager. As a workaround, in Flows use the exec node to run `chmod` commands to update file and directory access.
* The first flow created in Flows Manager cannot be stopped or restarted in Safe Mode. |
| **Applications:**
* Attempting to deploy an application may result in a `409 Conflict` launch error.
* The container terminal incorrectly prints `\x08` instead of deleting characters when the Backspace key is pressed. |
| **Integration:**
* Updating the **Bulk Insert Count** from `0` to any other value causes connectors to enter a failed state.
* A `bulk operation limit of 1000 exceeded` error message displays when performing a bulk edit on less than 100 subscriptions. |
| **System:**
* Static routes are lost when a network connection is manually disconnected or briefly interrupted. The Web UI retains the route configuration, but the backend routes are deleted. As a workaround, add the routes again manually.
* After a system reset of an `.iso` deployment, certain services (such as DeviceHub API, Analytics API, and Message Broker) fail to initialize and remain in a failed state regardless of subsequent reboots.
* LDAP searches can return an excessive number of records resulting in a `Size Limit Exceeded` error.
* Importing a template with multiple connectors failed when a configuration issue occurred with one component.
* Manufacturing Connect Edge may close unexpectedly if you delete all analytics groups in the system and then attempt to create new processors. |
