Re-install the App on my Android phone having gone PremiumFORUMS HOME SEARCH FORUMS

So I signed up and gained a free account on my PC

Followed the instructions and successfully installed the App on my Android Galaxy 10

All was good

I then decided to go Premium, everything seemed OK

Until I couldn't get the voice instructions on my mobile

Read the Q&A's and realised I needed to uninstall and re-install the App to make it work

So I tried but when you type into the Google browser www.plotaroute.com/mobile/ on my phone the next page does not give you a "Download" buttom

However, he instructions cater for this eventuality by telling you sign out of your account and to tap the Google 3 vertical buttons on the top rh side of the page and choose ADD to Home Screen

Unfortunately I'VE NOT GOT THAT OPTION ONLY ADD to "DESKTOP SITE"

Can anybody help?
