I'm not sure of the exact reasons for the shortage but one possibility is supply chain disruption from the pandemic. The base materials are often produced in huge batches over a period of years and then stockpiled while the plant is reconfigured for another drug. If the demand fluctuates and the stockpile is not enough to cope, it can take months to get back on track.
Definitely seems like a contributor. I wonder, also, how much of the delay was because pharmacies were told that the generic was coming, decided not to buy much of the more expensive stuff and hoped their stock would get them by until the generic was readily available.

I had no idea a generic was available, that should be good news. I hope there's no pharmaceutical shenanigans, AKA patent extensions.
