For me the official Samsung 45W charger is available on Amazon and it's at a discount right now. It arrived in the mail a couple days ago and works perfectly with my Note 10+, which is also compatible. https://www.amazon.com/dp/B07VHDSNNT/ref=cm_sw_r_apan_glc_i_NMTN3RK8V2ZHSW0CABED?_encoding=UTF8&psc=1

Just saw the 45W on sale at Amazon https://www.amazon.com/dp/B07VHDSNNT/ref=cm_sw_r_other_apa_i_WXPEEbC0PQZX1
They're $35 on Amazon. https://www.amazon.com/dp/B07VHDSNNT/ref=cm_sw_r_apa_i_eYZREbTZ9GAPX
Is this not the latest? https://www.amazon.com/dp/B07VHDSNNT/ref=cm_sw_r_apan_glt_i_A2ZBGFB4SXXC2YBJFG17
The S7 supports up to 45W fast charging, which the adapter you are using cannot supply.
You'll want something like this, or a 3rd party equivalent.
I thought about it, but Rule 5 on the wiki says no promoting the sales of items. I realize now that they're referring to personal sales, but I wanted to be safe at the time. Here's the link.
