Hi. Are you having trouble responding to questions people put to you?

Hi Luke , i was trying to leave some advise / comments to some questions put by Houzz readers .
No forwarding email address shown or at least does not come up in the recipient section of the email . ! So how does one best respond to questions raised ?
Also, on my iPad there is a choice of reading Houzz either by the "browser " or the "apps . ( but not on the iPhone - why ? )
"What's the difference between the two and which is the best to use .
Also ,why and what's the difference between the iPhone an iPad versions .
Where can I get more details on how to use Houzz .
Thanks all. Gary Protek window tinting ( Tasmania ) .
Can't seem to get into my profile on the iPhone to make a permanent change / alteration to my profile business name which ends with glane51 which I do not how that came up an need to alter. Thanks .
