Katie, I will ask support to reach out, there is no built in limitation. Depending on connection speed, I have noticed that my Siri will sometimes take awhile to load even short dictation - for example, when I am in downtown Chicago, Siri is almost unusable. We'll do what we can from the app side! While you're waiting for support to reach out, maybe check if you can dictate the same note you were trying in the RE note into an email or phone notepad. thank you so much! Jenn
