iPhone Reminders app iCloud Sync Issue "Activity Indicator" never stops

iOS 13 Hosed my reminders. Since then I abandoned the reminders app. I decided to try fixing it again. I have done all the things I could find online. Reset - erase all content in settings, turn off reminders turn back on and even created a new iCloud account to see if the issue was account-related or iPhone-related, and everything in between. It is account-related. My iCloud syncs between my mac and iCloud.com without issue. Recently - I don't know why - reminders from iCloud appeared on my iPhone. The Activity Indicator is spinning but there is no progress. I added a reminder in Icloud.com which did not sync to the iPhone. I added a reminder on my iPhone which did not sync to iCloud.com. I set the iPhone up to never turn off and left the reminders app open. It's been 4 days and the Activity Indicator is still spinning and no changes.

I believe this to be a server-side issue and there there is something wrong with my account. Does anyone have suggestions on things to try before I contact Apple Care? Does anyone know how to escalate this to engineers quickly?
