The greatest challenge faced by PWAs is a lack of education and implementation. Because PWAs were created by Google, other brands have been slow to adapt their devices to support PWAs. Despite being nearly a decade old as a concept, there hasn’t been nearly as much usage as anticipated.  There is also the question of costs. PWAs can be expensive for companies to build themselves and often complicated to design and operate. Without a total investment into the process, companies can be hamstrung by half-completed projects.
