Hi, i just send a transaction of 0.00012 bitcoin, and a fee of 200 satoshis, and now appears only unconfirmed, two hours and still nothing, i think i gonna change my wallet, anyone know how fix this pls? 
If you are manually put the 200 sat as your fee without using the dynamic fee or the slide button there's a possibility that your transaction can be confirmed slow. If you have lots inputs in your transaction and pay a low fee expect for slow transaction.
If you have some extra bitcoin you can increase the transaction fee by "child pays for parent".
Electrum is the best wallet honestly and I use it for along time never had any issue except for slow transaction but you can increase your transaction and fix your issue.
