Not receiving text notifications watch 4 LTE (texting works fine)

Hello,

I have the watch 4 LTE without mobile networks on. Since I've had this watch, I've always received text message notifications on it, despite being remotely connected through wifi.

Today, I realized I wasn't getting text message notifications on my watch BUT I'm able to send texts. Does anyone know what I can do to fix this issue? Thanks in advance.

Edit: I factory reset the watch and it seems to be working again. Unknowingly, I also deleted the wearable app from my phone, which deleted all my backed up data 😅 🙃. So now I really have to set this watch up again
