おはよごぜいます

I am new to learning Japanese, I have learned a small amount in the past and I am not at a level yet where I could comfortably have a conversation with a human.

I recently bought japanese from zero book 1, after watching the first 10 or so videos and loving じょーじ and his love and humour involved with his teaching.

I struggle to use pc's/macs at leisure because...I dont have one. Weird, right?

I noticed on the website there are quizzes I can do, but whenever I try to use my phone (android - galaxy s10) i get an error saying flash is not supported, and there is information on how to fix this if using chrome safari or Firefox.

Does anyone have a fix for android?
