It only appears occasionally. I have no alarms set, no timers, stopwatch etc. running.
Android phone. Searching got no joy.
Update: it was a scheduled message in signal. Didn’t want to send my bestie memes too late at night. It does use the actual alarm icon though, weirdly.
Thanks everyone for your help!
Great idea. Off to do that and hard kill the app. Will report back.
Edit: cleared cache and data and forced stop. No joy :(
Ugh. Glad to see you found the answer in the end though 😁👍
