https://us.community.samsung.com/t5/Galaxy-S25/Calendar-modifying-events-in-a-series/m-p/3128910#M3329 I checked some other entries of recurring and they are working too now. The one thing I didn't mention which may be a workaround is I went to my s24 for the event I wanted to change I changed it there and then let it sync to the s25 and since then everything on the s25 ultra is working. I checked the few other repeating entries and I was able to modify just one. Sun, 02 Feb 2025 19:49:09 GMT msz1261 2025-02-02T19:49:09Z
