DTV America era; going digital, return to Azteca, and additional networks
Around the time of the sale to DTV America, the station launched their digital signal on channel 38 via a flash cut. In addition to MundoMax on 38.1, WTSJ-LP resumed their affiliation with Azteca on 38.2, with both signals transmitting in 720p. With the move of WTSJ-LP to digital operations, it was the last station in the Milwaukee market to end analog operations. Slowly, DTV America began to establish their common template of having multiple subchannel networks on one signal seen in other markets.
In December 2015, Azteca was replaced with Buzzr and the feed was converted to 480p.
On May 5, 2016, the station launched a third subchannel for the Katz Broadcasting network Escape (the current day Court TV Mystery), which eventually transitioned to Katz sister station WTMJ-TV (channel 4).
In late October 2016, WTSJ-LP again resumed carrying Azteca on their main channel, its third affiliation round with the network, as the moribund MundoMax network began to wind down operations. In addition, a fifth subchannel carrying The Country Network was added. This returned that network to Milwaukee after a year-long absence, since WCGV-TV had dropped it from their second subchannel for Comet along with the AccuWeather Channel on a seventh subchannel (using the national feed without local conditions). Eventually the sixth subchannel was filled by Tuff TV, and all three subchannels were remapped.
With WTMJ ending their carriage of Cozi TV at the start of 2017, WTSJ-LP dropped Escape in the month before as WTMJ picked it up in its place. WTSJ-LP3 was left vacant with a paid programming loop until January 15, 2017, when WTSJ-LP completed the exchange and added Cozi TV for several months until July 27, when that network became exclusive to WIWN (channel 68).
With HC2 Holdings' mid-2017 acquisition of DTV America and the November 2017 acquisition of Azteca, the station became an owned and operated station, though its new ownership began to wind down most local operations and promotions. With the repeal of the Main Studio Rule in 2019, the station's studio and office on South 108th Street in West Allis was closed, and it is now centralcased out of what is now Innovate's programming hub with no local presence.
On October 25, 2019, WTSJ-LP went temporarily silent as an after effect of the operators and engineers of the Milwaukee PBS tower adjusting the tower's various antennas before and after the market's October 18, 2019, FCC-required frequency shifts involving the spectrum auction. WTSJ-LP also shifted to a post-repack channel of channel 26 and when it did, took an "LD" channel suffix.
Azteca America discontinued operations on December 31, 2022, with Innovate replacing it with Timeless TV, a network run by Burlington-based Canella Media. By the next month, Spanish programming had returned to the station's main channel, and it carried the Visión Latina network until the start of 2025, whens witched to the Fubo Sports Network.
