I had this issue on Fairphone 3 and now on my new Fairphone 6, not rooted, running 3.1.4-a15-20250915526528-official-FP6.
Someone poses a question on a Discourse based forum. I search for answers in a new tab, select relevant text, select copy, but when it comes to paste it offers things like translate with DeepL and 3 other options, none of which are paste. I don’t have this issue ever in SR Iron browser.
Just to add this is an intermittent issue, but still annoying.
I have seen this behaviour. I will try to capture a screenshot but it seems to me as if the “Context sensitive” menu fails to detect the expected “context”.
My workaround is to use a keyboard with Ctrl that is Unexpected keybboard, juloo.keyboard2 – now ^V will paste when required.
