Both my wife and I lost all our correspondence for the past 3.5 years (except for the very first message and the very last one). Neither of us had clicked on any of the above-mentioned buttons in order to clear history. Whom do we contact at Telegram in order to have this glitch thoroughly investigated? Is our suddenly lost correspondence still kept on some backup server?
I’m planning to post on LinkedIn about this inexplicable occurrence — perhaps someone else went through this and knows the answer.
