New poco f6 MI messages scheduled message pop up saying it failed to send

[deljanin]

So i wanted to set a scheduled message, although i did not know at a time that it does not work. Okay, no problem, but now there is a pop up saying that the message failed to send with option to resend it or to discard it. No mather what i choose between the two it still pops up again all the time. I tried wiping data off the app, clearing the cache, in the end i switched to google messages and the message still pops up and is very annoying. Any idea how to fix that?
