does this keep happening after trying to reconnect? My question might seem odd, but did u try different accounts in order to check that it isnt a Minecraft issue that happens on one account but rather an issue with your computer (Networking settings, Proxies, and so on)
If you are trying to purchase games as a gift from certain regions, it wouldn't let you do so, The only region I can remember right now is Egypt.
Which region did you choose while buying?
I have a 1.21.1 realm and it's working just fine, can you please provide more details related to the subscription plan? I think mods can help
Attaching screenshots would help a lot, can u also share the world files?
Can Confirm on a Samsung A15 8gb ram (Helio G99), and a Redmi Note 11 4gb ram
The Lag spikes mostly happen randomly, they last around 0.3-0.5 secondsĀ
