The favicon does not appear

Hi guys, I started bing webmaster 3 weeks ago via import sites from google search console. My site was indexed correctly and sitelinks also came out unlike google which first appeared and then disappeared. Now my problem is that I put a favicon for my site that this favicon appears on google while not yet for microsoft bing, I added the favicon 4 days ago it's normal that it doesn't show up yet on microsoft bing. I also submitted the sitemap to both google search console and microsoft bing
