Hi @Rick Wesley ,
If you are using free pricing the max number of pages training is 500, please refer to this Service Limits page and Pricing related information.
To increase the training limit, we can open a support ticket. Please let me know if you have no support plan, I am happy to enable you a free one for this case.
If you are looking for support ticket, please send me an email at Azcommunity@microsoft.com with this thread, your Azure Subscription ID and title it as Attn: Vasavi, will take care of it.
I hope this helps.
Regards, Vasavi
