I keep having connectivity issues with my new earfun earbuds. I bought the earfun air pro 4's on Amazon the other day and while they connect fine, they don't connect automatically. Every time I open the case, it tries for a few seconds before entering 'pairing' mode, then I have to open settings on my phone, go to Bluetooth and press 'earfun air pro 4' to force it to connect. This happens 75% of the time, with it rarely connecting automatically. Does anyone know why? Thanks
ps. I have an iPhone 13 and I use the earfun app
