Hi there.
We appreciate you bringing this issue to our attention. A possible reason for this could be a data problem within your system. I’m here to provide some browser troubleshooting steps to help isolate the issue.
Before anything else, could you please specify which sales form you used with your custom form style? Additionally, have you encountered any specific errors? Providing detailed information and a screenshot would be very helpful.
In the meantime, try clearing your browser's cache. This can help free up space and may improve your device's performance, as many issues are often related to browser settings or the cache itself. If the problem continues, consider switching to a different supported browser for the best QuickBooks experience.
Additionally, I've included this helpful article for your reference: Customise invoices, estimates, and sales receipts in QuickBooks Online.
