AHA! I’ve managed to resolve it and in the process, found the errors of my way! I dragged a ‘button’ into the repeater (mobile mode). Which, under normal circumstances, works fine. What I had to do was create a button from ‘web’ view. So, I deleted the original button, went to web view, added a new button, then DO NOT CLICK THE BUTTON LINK. You have to click the repeater itself. Not a single item, but ensure the WHOLE repeater is selected. You’ll see a blue box around the entire repeater, not just the item. Then click the connect icon and you’ll see ALL the links (texts, images, buttons etc). Select the button, then click link. From here, you’ll see the dynamic page WITHOUT THE SPECIFIC BAR NAME (in my case). So, it’ll link to the dynamic page properly.
Hope this helps everyone. Still, WIX should look into this, enable button links form mobile creation and/or enable dynamic linking from the item select ,not just the repeater select. I don’t see the point in having the dynamic link that doesn’t work. It’ll just frustrate people and add to WIX support logs!
