Hi Kritty796,
Thanks for your post.
My apologies for the late reply. We regret to hear that you and your customers are experiencing issues when trying to view all activity for an invoice. I appreciate your patience and for reaching out about this. Allow me to help you with this. Regarding the activity history, I've further checked and replicated this on our end, and it seems to be working fine. In this case, I would recommend clearing the browser cache, as this helps your computer or device run optimally, and doing so can help fix certain problems, like formatting or loading issues. Signing out and signing back in again can also help with loading issues.
If the issue persists after clearing the browse cache, please let me know so I can further investigate.
Otherwise, if my response has answered your inquiry, please click "Accept as Solution" to help other users find this.
Kind regards,
Shella
