Need help getting my spam filtering to work like it used to

I have had my Comcast email from the day it was switched over from erols email- yes, that long!  About the fall of 2022, the spam filtering for my account seemingly stopped working.  I pick up my comcast.net email through thunderbird on my laptop and apple mail on my ipad.  Every day I have spam in my inbox and genuine messages in my spam folder.  Every day, I log into my xfinity email at connect.xfinity.com and tag emails as spam or not spam.  The spam filter does not seem to be learning from this.  I don't know what happened to my account last fall that started this.  Can anyone help?
