I have created an SPFx banner as attached. The issue is that I see multiple banners pops up as SharePoint site at times pulls from the history. When I do a refresh, then the single footer and banner appears.
I would like to know why the issue is and how to get it resolved.
Please refer my attached image.
Thanks
Hi @AniruddhaAditya-3867 ,
What browser are you using? Could you provide more information to help us reproduce this issue?
@AmosWu-MSFT Yes. This issue is resolved. by using a weired code as below
if (DuplicateChecker == 1) {
this.renderBanner();
DuplicateChecker = 2; //This is to stop duplicate banner appearing when page loads from cache
}
}

I am using Chrome 88.0.4324.150 (Official Build) (64-bit) and IE also. This issue comes when SharePoint loads the page from the history/cache.
Thanks

I created an application customizer extension example in the SPFX document, but I did not successfully reproduce your problem. You can try to clear the browser cache. If it is convenient, please provide your spfx for testing. If there are some private information in the code, please delete or replace them with other words.
What are the columns and values in the two lists of BannerConfigration and BannerMessages?
It is a custom list with title and another column with Single Line of text.
HTML code of the header has been printed. You could check the number of times the header HTML code is printed and whether the printed content is the same in the console window of the browser developer tool.
I suggest you debug on the browser to see if there are logic errors in the code.
