Question about resetting hub

ok I am really annoyed with myself as I type this I think god what an idiot, everyone will be laughing right now. Believe me I could kick myself.

since the update all my device’s played up, I found a post that said to try deleting the hub …
didn’t realise until to late I needed my code, guess what I cant find - bugger!!

in my defence it was like 1am and I wasn’t thinking.

I have sent a email requesting help on this whilst I don’t think that will be a problem what I need to know apart from the tedious job of replacing 3 years worth of work will I have to run a hard reset on the hub?

this is so can do it in advance.

has anyone else been in this position before any tips or advice?
