Any one else facing network issues in 5g?

Recently i ported from airtel to Jio after seeing how fast the network was. True to its word, I haven't had a single problem since i ported back in January. The internet speed is fast, upto the standard of my city.

But since the past few weeks, I've been facing issues just like I did with Airtel. The internet connection is slow, internet switches between 5g and 4g without notice, and the overall experience is frustrating. Is there a way I can fix this? The plan I use is the rs. 349/28 days, 2gb daily—with 5g unlimited top-up.
