CFI not matched on SELECT event of Rendition in Mobile and Desktop

[RatulSikder97]

When I annotate by the selection, I get different CFI in Desktop and Mobile. I have used Firebase Firestore as annotation storage. I store CFI of selections. So, When again the book is re-rendered, an error is emitted. "No startContainer found for epubcfi(/6/6[id221]!/4/6,/1:40,/1:46)"

Can anyone kindly help me?

What CFI do you get in desktop and mobile? I find it very strange as we are also using epub.js on both desktop and mobiles and did not see such behavior.

I get epubcfi(/6/4[Section0001.xhtml]!/12/6/2,/1:0,/1:8) in desktop and epubcfi(/6/4[Section0001.xhtml]!/4/6/2,/1:0,/1:7) in mobile for same selected content. For so, I can't sync annotation between cross devices(mobile and desktop web reader).
