UPDATE!!!

[Stornaway]

Anyone receiving pop up message constantly preventing access to sites.
Reads Samsung internet has stopped or stopping. Send feedback. Close app or reopen app.
Security and scan checks show nothing adverse but clearly there is major problem.
Not a wi fi problem either.
Any help or advice please for my Samsung iPad.

@Stornaway: Please can you try heading to Settings > Apps > Choose Default Apps > Opening links > Open Links In Apps, and toggle this option off. If this doesn't help, head to the Galaxy Store > Tap the 3 lines in the top left > Updates, and check for any available updates for the Samsung Internet app. I'd also recommend opening the Samsung Internet app > Tap the 3 lines in the bottom right > Settings > Privacy and Security, and exploring your options here.
