There is a Progressive app, that looks and acts like a regular app. I posted the steps to get in this post
How do iPhone users access this App ?
- Open the site in Safari
- Tap Share
- Tap Add to Home Screen
- Done — it behaves like an app
Yes I have the THS App - I misunderstood , I thought you said that you have a separate forum App -
@BonnyinBrighton and @co_ri_na figured it out! 
In @co_ri_na 's screenshot the THS Forum is the white app icon on the left and THS is the green icon on the right.
I have the same view. You’ve just installed the progressive THS app we discussed above.
The problem for me is you cannot be logged in via both apps.
Hmm, that’s strange, the two platforms are independent of each of other. What error message are you receiving?
It simply shows me as logged out when I switch between the two apps. If I log into one it logs me out of the other one…
That’s interesting. So I did some research and it turns our Safari thinks forum.trustedhousesitters.com and trustedhousesitters.com are the same domain. So it overwrites the cookie set by one site because well it thinks it’s the same site. Android is smarter in this case and keeps both separate. A quick solution will be to add the Forum app in another browser like Google Chrome.
I am the same @BunnyCat so I never have to find & follow a link to the forum
I am late to the party. I noticed the way to navigate to the forum changed some weeks ago. In frustration, I just google the forum now. Why, why, why is every technical change on ThS negative? I am not a combined member and why that should matter makes no sense. This is not streamlined. This is illogical and confusing. Can anyone explain to me what is gained by this tweak? There is a saying that change is inevitable. For THS it is inevitable that every change will break something else.
Mind is still here also. I have never used the app though only the website.
