OK, closed Vivaldi, Vivaldi (Chrome based), after clearing cache and cookies. Opened, and not showing. Closed it again. Open Opened Chrome (vers. 85) and pasted the copied address from Vivaldi into Chrome and all edits are showing through. Either the bus lane edit resolved this or it's just bad cache clearing behavior by Vivaldi. For now, consider case closed. If I can edit the OP title i'll add [RESOLVED] to the title. Apologies for the interruption.
