You've reached the current usage cap for GPT-4, please try again after 2:04 PM

Ive been a plus subscriber for like 6 months. First time I have seen the cap of gpt4 this morning. I have had some very heavy usage prior to today and never saw a cap. I sent maybe 10 messages this morning and I’m capped for 3 hours. I gotta think theres something wrong happening. This isn’t normal
