Can't open Android Telegram

Xperia X still in 3.4.0.24 Pallas-Yllästunturi, today using Telegran FOSS 8.0 i received a message from telegram “your version is too old please update…” ok i update Telegram FOSS to the latest version of F-Droid 8.2 still compatible with android 4, now with this version Telegram doesnt open.
Any ideas or solutions?

Thank you.

Well… uninstallig older version and installing it from zero works, at least for me, if anyone is in the same situation.

Merry xmas for all.
