So I got a alert for Amex about my credit and it says my credit went down 24 points but I paid evetjimg off and had no late payments but then I go on Experian and it says my credit went up ? Any idea what may have happened ?

I have business and I just got accredited for the Amex blue business plus and I need to a little more funds to use fund this bigger project and I don’t want to pull from personal Accounts reason is my agent told me to not mix personal and business what other card should I apply for ? And how long should I wait to apply for that card ? Any advice
