Flex 2 stopped syncing with my Sony Experia

[Brambl3]

My flex 2 has stopped syncing with my Sony experia. Have reinstalled the app, restarted the fitbit, disconnected Bluetooth and still won't sync. Have tried to 'chat' with support but no response.

 when there is someone available, chat is an option. Phone or Twitter works well, too.

Am in England and having difficulty accessing the chat - intermittently
available 😞
The last chat said to upgrade my phone to android 10 but my phone won't
support that version as it's now too old 😞

@Brambl3  you try calling the UK number? As our phones get older and the apps get newer, it's harder for the phones to keep up. I'm on Android 9 myself and it's time for a new phone.

Thanks I'll try again to contact them, I just don't want to have to buy a
new phone just so I can sync my fitbit!
