HeyGen CS — TTS broken for us:
POST /v3/voices/speech HANGS for any NEW text (0 bytes, 20–60s timeout).
Only cached「你好」returns in ~1.5s (same audio id every time).
Clone voice fbff3892add74ba589aebfde1b13bb26 (Jackie) + re-clone 5b9229e9702f4b4cb903b3f4a7d2189b both fail new synth.
Wallet/quota OK; LiveAvatar sessions OK. Account: tinny.ting@bastillepost.com.
Need Jackie clone TTS restored — please check speech engine / stuck jobs.
Repro: unique text e.g. "測試編號42469" times out; "你好" hits cache.
