Problem description

I am experiencing significant delays in processing invoice batches using Azure Cognitive Services-Form Recognizer. Since September 1, 2026, most batches, each containing 15 invoice documents, are taking over an hour to complete, with some exceeding 45 hours. The expected processing time was within minutes, but now the process is extremely slow.

Environment

Azure Cognitive Services-Form Recognizer resource in the US East, using the asynchronous "invoice" prebuilt model via batch submission, with default service tier S0

Current status

I am seeking assistance to identify the cause of the slowdown and to find possible solutions to improve processing times.
