The last few days my Samsung Internet browser has stopped autocompleting addresses I type in the address field. This goes for both my Z Flip and Note 9, so it seems to be related to an update.
I tried clearing the App Cache and it seemed to work again for a short while, but the next time I started the browser it was suffering from amnesia again.
I have also tried clearing App Data and completely uninstall and reinstall the app.
My current version is 184.108.40.206. Android is the June 1 update on both phones.
