My WhatsApp (iPhone 2020 SE) has become flakey - it doesn’t always notify me of new messages, but they are there when I go into the app, or if I’m out they come through as a massive download when I get home and my phone picks up the Wi-Fi. WhatsApp calls sometimes work but mostly just show up later as a missed call.
I haven’t changed any settings. It’s set to use mobile data, and notifications are on in both iPhone settings and in the app.
Any ideas?
Or do I just need to delete the app and reinstall? Is there an easy way to keep chats if I do this?
