Calendar Issue

Hi 
I have done like  explained (https://community.powerplatform.com/forums/thread/details/?threadid=3404995c-a360-44cd-b3bc-02235465f026) with a Share Point list and it has worked fine for about a year but after this new year the event ID is changing after them being created. So after new year my flow failed every time they are being changed or deleted. 
 
I have tested to send an e-mail to myself with the event ID of a created event and it dont match the ID in the Share Point list
 
Does any one have the same issue?

    after new year, Outlook event ID changes when events are updated or deleted, causing flow to fail because stored ID in SharePoint no longer matches the real event
    solution:
    1. use iCalUId instead of ID to track calendar events
    2. after "Skapa händelse (V4)", add short delay (2-5 sec)
    3. use "Hämta händelse (V4)" to get full event details
    4. get iCalUId from response: outputs('Hämta_händelse_(V4)')?['body/iCalUId']
    5. save this iCalUId to SharePoint list
    6. when updating or deleting, use "List händelser" with filter
    7. iCalUId eq 'yourStorediCalUId'
    8. get the current ID from result, then run update or delete
    9. make sure SharePoint column for iCalUId is type text
    10. avoid using ID directly in future flows for calendar sync
