New update not working

Hi I saw there was an update available and decided to press the button after one hour it still says update in progress , I restarted the inverter as the post advised.
No progress what do I do now.
I have read posts about possible dongle jumbled up and needs work.
Unfortunately I’m not technically minded can givenergy send me a new dongle I can just insert into my inverter. Or contact my installer as only a few months old?

Bolts Contact them and they will help you sort it out. Web chat on the support page (if available) is best followed by actually calling them.
