POS machines should have been manufactured by now and deployed to ease payment especially in sales outlets. I believe this will encourage the use of not just bitcoin but other crytocurrencies. I don't think the failure of an app should cause an organisation to discontinue accepting Bitcoin as a mode of payment.
It should be encouraged as an alternative mode of payment especially by young people who, actually are the ones really driving new applications/usage for Bitcoin. Lightening networks should correct the disruptions in networks experienced during transactions. I suggest dedicated networks be built to sustain this aspect of bitcoin usage if possible.

I believe Bitcoin is the future of Internet funds transfer and payment systems.
