I used to love Medibang as my main app but the inclusion of ads interrupting constantly is unacceptable. Even saving sometimes won't help you, as you'll leave and come back to find half an hour of work is gone. The ads are intrusive and limit your capabilities, and as I said even the save function won't save you. As soon as I find an app to replace Medibang, I will. It's a shame, I've been using medibang for years. It's disappointing to see it in its current condition.
