Timeline creation error after uploading past notes

I uploaded previous notes for a client with multiple consultations and then clicked Create Timeline, but received an error message.

It’s unclear:

• Does the AI Timeline support clients with multiple past consultations?

• Is there a total data limit it can process? Specifically, is the 100,000 character limit applied to all consultations combined, or to each consultation individually?

• Or is it required to create and update the Timeline after each visit for it to function properly?
