Hi parth0907

1. TrueCaller App version - Cannot determine that obviously since it's on production.
2. Devices reproduced on - POCO M3, Redmi Note 9 Pro
3. Exact steps to reproduce - Cannot specify as it occurred in production. Saw this log -> [onRequestFailure] ==> failed to connect to api4.truecaller.com/35.190.118.8 (port 443) from /25.70.221.221 (port 41250) after 10000ms print 4 times. I suppose the user was facing internet issues.
4. TrueCaller SDK version - 2.6.0
