Please go through the following steps to find causes for your issues with Auto Plan Time for TEMPO.
1. APT uses the information in fields selected for User, Start Date, End Date and Estimation to create/update plan time allocations. For any issue please make sure that these fields have values and are not empty.
2. APT does not create plan time allocations just because it is installed on the system but responds to updates on issues that change one of the four issue fields set for allocation. Please make sure at least one of the four fields is updated (for example through the edit screen) and then check to see if the allocation is created.
3. If you still do not have an allocation created for the issue, please follow the steps defined in the link below. These steps will enable detailed logging for APT. Then once again update on of the four fields of the issue you are working on and send us the log output. (OBSS Plugin Support Portal)
