Neichi chikonzero, pakave nekukakavadzana nezvazvo kwenguva yakareba uye Lockdown ichadzimwa nekukanganisa, kunyangwe chikonzero chikuru cheichi ndechekuti inogona kukuvadza mashandiro aripo.
Iyo yekuvandudza yatove kuwanikwa kubva kune akasiyana software nzvimbo. Tichifunga nezvekureruka uye nekukurumidza kuri kuita kugadzirisa, mune dzidziso hazvidi kuti utangezve, kugadzirisa izvozvi.
