As an early comment said because you're using a web wallet even though it is a noncustodial wallet but AFAIK, almost all of them don't allow you to reduce the fee according to the mempool transaction fee size.

I find it bad as almost all of the networks are congested since almost this week and I even don't have a chance to move my Bitcoin into the other wallet.  I have heard a rumor that the consequences of China forced to stop mining due to energy issues has been a pain in the arse.  Bitcoin on the other hand can't be used for microtransactions especially today.  What I would suggest is, if you may find someone living overseas you may seek assistance from them to keep your assets to their non-custodian wallet that you can able to modify the fee, like for example Electrum.  In that way, you can save a lot of headaches.

Or else alternatively, I think you must use altcoins for your transactions.  In that way, you can still keep up and never ever use Bitcoin for transactions less than $100 which is definitely not recommended.
