Tags in the phone version

Leaving aside the fact that tags are not the best solution for organizing posts ( specially when the n umber reaches a high value ), I’m coming across the the problem that some patrons won’t even have that option ( navigating tags ) when they use the phone version, wether it is the app or web browser.
That, together with links working the bio section, where does it leave us when we need to find an old post or a series of them with the same tag? Any alternatives?
Thank you.
