op You may be used to using Metamask wallet so maybe you are telling others to use Metamask wallet but this wallet has some issues. I myself used Metamask wallet but Metamask wallet has many network problems. I stopped using it due to network issues. If there was no network problem then I would have continued to use it. Since I am suffering from this problem I said Metamask wallet network problem now those of you who want to use Metamask wallet can definitely do so
What exactly network issue you talk about? If it's about loading bar going on and on, then get the different rpc from whatever is default on from site like chainlist [1] for the chain you are having network issue and it'll be solved.
Metamask or any other wallet is just a tool to interact with chains, there can be no issue with MM itself technically.
