No message notification on lock acreen

iphone 13, after the recent update i've had the same issue others have regarding the phone randomly going to silent mode, the temporary fix is to toggle the mute switch back and forth. However; has anyone else noticed they are not getting text message notifications on the lock screen? i don't know if it's related to the other issue. This issue is that i can check my lock screen and not see any notifications, but then if i unlock it i will see the red number next to the message app. so i missed the alert on the lock screen all together. it's been very random, it could be from an unknown sender, or it could be from someone in my contacts that i text regularly. it's also random in that it can be during a conversation with a contact, it will simply not notify me of an incoming message on the lock screen. then later after a few texts back and forth it will start showing. it's frustrating and seems completely random. i've verified that no settings appeared to have changed since the update. alerts are allowed on lock screen, the message filter is turned off, the individual message conversation is not muted. i've tried restarting both the regular way and forced way. nothing seems to fix it. i'm up for any ideas, thank you
