@Rhishav generally problem with smaller ISPs as they have PMTU discovery disabled at their end. there can be genuine routing issues but that is rare. most of the consumer grade routers have no issues for mtu till 1450, for business grade routers Mikrotik users can confirm how painful it is with local ISPs. check it on cmd windows ping google.com -f -l1450 and keep on reducing it instead of google.com use your problematic site. for ipv6 remove -f from command

The thing is all this started happening only after we opted for PPPoE. On the old setup atleast everything was working flawlessly.
i use a pppoe setup ever since i installed i never faced any issues on alliance. It’s just that their ipv6 routes are sometimes really suboptimal like ~300ms latency to this forum over ipv6 whereas ~30ms on ipv4
MTU and MRU 1480 was not working for me. Was bit better but didnt entirely fix it. Called up cc. They informed to change it to 1472. Works flawlessly for me

I called them up regarding MTU and they said the device default of 1480 or 1492 are both good and did not mention 1472 at all.
8 bytes for PPPoE, 4bytes per vlan, 20bytes for ipv4, 40bytes for ipv6. it is not a bug with Mikrotik, it is professional grade router which needs perfect input to have desired output. Mikrotik is highly discouraged by small ISPs under PPPoE.
and if you use ipv4 & ipv6 then also do MSS clamping and 1452 will be MTU to handle ipv6
