iPhone SE only syncs Notes with Exchange if I create a new Note

I use AkrutoSync, which presents an Exchange Server interface to my iPhoneSE. If I create a new Note on my iPhone, it syncs with AkrutoSync. If I edit or delete a note, however, it won't sync even after half an hour. This seems to be an issue with iPhone SW and how it determines when to sync. Hence, the suggestions at https://www.akruto.com/fix-iphone-not-syncing-with-exchange do not seem to be relevant. The annex below contains the details of my phone/AkrutoSync setup. Is there anything I can do to troubleshoot this? ------------------------------------------------- **Details of setup between iPhone SE and AkrutoSync** The iPhone SE is as up-to-date as possible, iOS 14.4. The laptop runs Windows 10, and I install updates whenever I am prompted. AkrutoSync is version 5.2.42 (64-bit). To the iPhone, it presents an Exchange interface for Outlook 2019 (desktop) on the laptop. I choose to sync Calendar, Contacts, and Notes, but not Email. On the iPhone, I connect to AkrutoSync as an Exchange Server. I connect over home WiFi, not over the internet. The laptop's IP address is static, so that should not be a problem. The WiFi Access Point will dynamically assign IP addresses to other devices, but not to the laptop. -------------------------- **What I tried** For iPhone's Calendar app, I can manually initiate a sync from the iPhone by following [these few steps](https://apple.stackexchange.com/a/125743/254633) . However, there is no such counterpart for the Notes app. I found out from a commentor that iOS 14.4 was actually not up-to-date, which surprised me as I normally see a notification that an update is available and I update right away. I upgraded to the most recent iOS, version 15.2.1, which solved half the problem. The iPhone now initiates a sync if I edit a Note, but not when I delete a Note. I suspect this is not configurable, as I've never found indications of configurability for the years that I've looked.
