I use the samsung calendar app on 3 of my devices (s10, s7 and s5e tablet) as the widget for it is much better imo than the google calendar app.
Never really had an issue with it, until recently. Due to coronavirus, I had to edit a lot of my calendar dates and events in google on a pc on the website. Normally the samsung calendar sync's up fine, but now ive noticed any NEW events will sync file. DELETED events will sync ok. But EDITED events won't chance..
So in my case, several events that were postponed from this year to next, I edited the calendar entries to the new dates next year. One event seems to have moved fine in samsung calendar to next year, but the rest are all listing as still happening next month. Is my only option really going to be manually edit every single one again on each device?
