created · Wes Jago 4 Mar 2026 16:12Hi, I've noticed that when I try to export a report with more than a certain number of records, the export button just spins without completing. It's been happening for a couple of weeks. Is anyone else seeing this?- public_reply · Olivia Grant 5 Mar 2026 06:10Hi Wes, thanks for the report. Can you tell me roughly how many records you're trying to export? Also, which report template are you using? I'll look into what's happening on our side.
