For the past week or so my messenger is acting weirdly and it's driving me insane.
If someone messages me first and I reply then they deliver fine. However when the same person sends a second message (in reply to my reply) and I send one back it just goes grey with a white tick inside, not blue with white tick.
It's definitely not from anyone blocking me or anything (well they better not be, one it's happening with is DM). I'm helping to organise a virtual charity event at the moment too and some of the messages relate to that and people are waiting for my response, which are sat there grey infuriating me.
Does anyone have any tips to fix it please? I've tried logging out & back in and also uninstalling the app and installing it again but doesn't seem to make any difference.
