Hello. I have Hudl 2 with the Tesco keyboard case. Has been working fine til last couple of days. Keyboard failing to work although it was shown as 'Connected' in Bluetooth sttings. Suspected charge may be too low - charge lasts ages so easy to overlook - so left on charge overnight. Keyboard still not working but now not even detected by Hudl 2. Tried with charger plugged in to Keyboard. No difference. Tried with separate Bletooth keyboard and that works fine so am suspecting keyboard failure. Any thoughts on whether can get it back working ? Thanks for reading.
