Tweets not showing up in hashtag searches

Hey, A few days ago my twitter account was working fine, but then, on morning Twitter app kept logging me out, and I signed in every time I opened the app, then later I realised my tweets with hashtags arent showing up in hashtag feeds, I deactivated my account for 48hrs to see if anything changes back to normal, but it didn't, I dont even know how to contact Twitter for help, I tweeted to @support, but they didn't reply back, pls help
